Serves for the fault-tolerant return of a reference to an existing object or an occurred error code.

The specialization ara::core::Result<T&, E> encapsulates either a non-owning reference to a successful operation result of type T& ([SWS_CORE_00902]) or an occurred error code of type E. Users typically check for the presence of a value via HasValue() ([SWS_CORE_00918]) before accessing the referenced target object via dereference operators or Value(). Since the instance does not own the referenced object itself, the caller is likely to need to ensure that it remains valid in memory throughout the entire duration of use of the result. Question Q-48d71186fb35af77 (open)

Context

The template specialization ara::core::Result<T&, E> encapsulates either a reference to a successful operation result of type value_type ([SWS_CORE_00902]) or an error value of type error_type ([SWS_CORE_00903]). As a standardized return structure in module core, it enables error-robust programming without the mandatory use of C++ exceptions in regular operation. According to the specification, the implementation enforces at compile time that the error type E corresponds to the type ara::core::ErrorCode; a deviating assignment leads to a compilation error. Interaction partners include data-supplying services, calling components for result checking, and the externally managed target object, which is accessed directly via the bound reference.

Lifecycle

An instance is deterministically initialized either with a reference to an existing lvalue or with an error. Initialization with a reference is performed via the constructor [SWS_CORE_00908] or the static factory method FromValue [SWS_CORE_00904]; passing rvalues is not permitted. Error states are created via constructors ([SWS_CORE_00909], [SWS_CORE_00910]) or factories such as FromError ([SWS_CORE_00905], [SWS_CORE_00906], [SWS_CORE_00907]). A default constructor does not exist. Copy and move constructors ([SWS_CORE_00911], [SWS_CORE_00912]) take over the current state of another instance.

Regarding ownership, Result<T&, E> merely binds a reference and assumes no ownership or lifetime management for the referenced target object. The caller is therefore likely to have to ensure that the target object remains valid over the entire lifetime of the Result instance. Question (open) State transitions during ongoing operation are performed via assignment operators ([SWS_CORE_00914], [SWS_CORE_00915]), which rebind the internal reference to the new target or transfer an error. In addition, EmplaceError [SWS_CORE_00916] puts the instance directly into an error state, while Swap [SWS_CORE_00917] swaps the contents of two instances. The destructor [SWS_CORE_00913] behaves trivially, provided that E is trivially destructible. Concurrent read accesses to value or error are thread-safe, whereas state-modifying operations such as assignments, Swap, or EmplaceError are not thread-safe.

Usage Path

The regular flow includes state verification and purposeful evaluation:

State check: Before accessing, the caller checks whether a value is present via HasValue() [SWS_CORE_00918] or the conversion operator operator bool [SWS_CORE_00919].
Direct access: In the event of success, Value() ([SWS_CORE_00924], [SWS_CORE_00925]), operator* ([SWS_CORE_00920], [SWS_CORE_00921]), and operator-> ([SWS_CORE_00922], [SWS_CORE_00923]) provide the reference or a pointer to the target object.
Optional and fallback-based accesses: Via Ok() ([SWS_CORE_00926], [SWS_CORE_00927]), the reference can be converted into an ara::core::Optional. The method ValueOr() ([SWS_CORE_00933], [SWS_CORE_00934]) returns a copy of the referenced value or a passed replacement value.
Monadic operations: With Bind() [SWS_CORE_00941], a transformation function is applied to the reference and the result is wrapped, while errors are automatically forwarded. In case of errors, Resolve() ([SWS_CORE_00939], [SWS_CORE_00940]) invokes a replacement function that provides a compatible reference.

Sequence diagram: Typical query and access steps for value and error. Sources: [SWS_CORE_00918], [SWS_CORE_00924], [SWS_CORE_00928].

Error Scenarios

If the instance is in the error state, the overloads of Error() ([SWS_CORE_00928], [SWS_CORE_00929], [SWS_CORE_00930]) grant access to the error object. In addition, the error can be obtained via Err() ([SWS_CORE_00931], [SWS_CORE_00932]) as Optional<E> or via ErrorOr() ([SWS_CORE_00935], [SWS_CORE_00936]) with a fallback value. For specific error comparisons, CheckError() [SWS_CORE_00937] compares the contained error with a reference error.

The specification defines strict preconditions for element accesses:

ResultWithNoValueViolation: A call to Value() ([SWS_CORE_00924], [SWS_CORE_00925]), operator* ([SWS_CORE_00920], [SWS_CORE_00921]), or operator-> ([SWS_CORE_00922], [SWS_CORE_00923]) on an instance without a value represents a specification violation.
ResultWithNoErrorViolation: Accessing Error() ([SWS_CORE_00928], [SWS_CORE_00929], [SWS_CORE_00930]) when a value is present violates the preconditions.
Exception handling: In the event of an error, the calls ValueOrThrow() ([SWS_CORE_00938], [SWS_CORE_00949]) throw the exception associated with the error; they participate in overload resolution only when C++ exceptions are enabled in the compiler.

Constructors and destructor

Result function 5

Construct a new Result containing a reference to value from the specified reference to value. If U is not an lvalue, the program is ill-formed.

Overloads Result 5

template <typename U = T> Result (const U &&t) noexcept; SWS_CORE_00908

Methods

Bind function

Apply the given Callable to the value of this instance, and return a new Result with the result of the call. The Callable is expected to be compatible to one of these two interfaces: • Result<XXX, E> f(const T&); • XXX f(const T&); meaning that the Callable either returns a Result<XXX> or a XXX directly, where XXX can be any type that is suitable for use by class Result. The return type of this function is decltype(f(Value())) for a template argument F that returns a Result type, and it is Result<decltype(f(Value())), E> for a template argument F that does not return a Result type. If this instance does not contain a value, a new Result<XXX, E> is still created and returned, with the original error contents of this instance being copied into the new instance.

template <typename F> auto Bind (F &&f) const -> <see below>;

CheckError function

Return whether this instance contains the given error. This call compares the argument error, static_cast’d to E, with the return value from Error()

use

The member function const T * operator-> () const noexcept enables synchronous read access to the referenced value of a ara::core::Result<T &, E> object [SWS_CORE_00922]. It takes no arguments and provides a const pointer (const T *) to the referenced target object as its return value [SWS_CORE_00922]. For usage, header #include "ara/core/result.h" must be included [SWS_CORE_00922].

Error handling

The operation is declared as noexcept and possesses the property exception safe [SWS_CORE_00922]. If the object contains no value, a precondition violation (violation) ResultWithNoValue occurs [SWS_CORE_00922]. Callers must therefore ensure before dereferencing that the instance indeed holds a valid value.

Concurrency and Limitations

The function is specified as thread-safe [SWS_CORE_00922]. Since it is a const member function, concurrent read access to the same instance is safe. However, access to the target object itself is subject to the thread safety guarantees of type T.

Interaction

The operator constitutes the const counterpart to the non-const overload T * operator-> () noexcept [SWS_CORE_00923]. While the non-const variant returns a modifiable pointer T* [SWS_CORE_00923], this version enforces immutable access to the referenced instance.

use

The member function operator-> enables direct access to the referenced value of an instance of ara::core::Result<T&, E> according to [SWS_CORE_00923]. The function requires header file #include "ara/core/result.h", takes no parameters, and returns a pointer of type T* to the contained or referenced value. The call is executed synchronously and is declared with noexcept.

Error Handling and Boundary Conditions

If the object contains no value at the time of access, a specification violation in the form of a ResultWithNoValue-Violation occurs [SWS_CORE_00923]. Specific DET or DEM error reports are not designated for this member function. Regarding concurrency and fault tolerance, the operator is classified as thread-safe and as exception safe [SWS_CORE_00923]. Callers should presumably ensure before the call that the instance indeed holds a valid value to prevent triggering the violation. Question Q-a4b13cd34a40eb19 (open)

Interaction

In interaction with template ara::core::Result<T&, E>, this non-const member function complements the corresponding const overload const T * operator-> () const noexcept from [SWS_CORE_00922], which is subject to the same guarding rules but provides a read-only pointer (const T*).

function ValueOrThrow [SWS_CORE_00938] Upstream: RS_AP_00130

const T & ValueOrThrow () const noexcept(false);

Return the contained value or throw an exception.

The synchronous member function ValueOrThrow of template specialization ara::core::Result<T &, E> enables access to the contained value ([SWS_CORE_00938]). Upon successful operation, it returns a const reference (const T &) to the encapsulated reference target.

If the object represents an error case, the function throws the exception associated with the specific error (noexcept(false)) ([SWS_CORE_00938]). The specification explicitly classifies the exception safety of the operation as not exception safe (not exception safe) ([SWS_CORE_00938]).

Regarding concurrency, the method is declared thread-safe ([SWS_CORE_00938]). A major constraint concerns the build configuration: if C++ exceptions are disabled in the compiler toolchain, ValueOrThrow does not participate in overload resolution ([SWS_CORE_00938]).

Within header ara/core/result.h, the function constitutes the const counterpart to the non-const reference overload [SWS_CORE_00949]. For regular value types, analogous overloads are provided for lvalues and rvalues ([SWS_CORE_00766], [SWS_CORE_00769], [SWS_CORE_00778]), whereas for ara::core::Result<void, E>, an overload without a return value is defined ([SWS_CORE_00866]).

This usage note was generated automatically based on the R25-11 specification.

function ValueOrThrow [SWS_CORE_00949] Upstream: RS_AP_00130

T & ValueOrThrow () noexcept(false);

Return a reference to the contained value or throw an exception.

AI-GENERATED unreviewed Model: gemini-3.8-flash-medium · Effort: medium · Temperature: not controllable · Prompt: cc4ce28e1dcf Provenance

translated from the German guidegemini-3.8-flash-low · 2026-10-13 · German original

The member function ValueOrThrow of template specialization ara::core::Result<T&, E> is used for synchronous access to the contained reference value [SWS_CORE_00949]. It takes no parameters and returns a non-const reference T& to the stored value [SWS_CORE_00949].

If the object contains an error rather than a value, the operation is not exception safe (not exception safe) and throws an exception of the type associated with the error (noexcept(false)) [SWS_CORE_00949]. An essential constraint for its use is that the function does not participate in overload resolution if C++ exceptions are disabled in the compiler toolchain [SWS_CORE_00949].

Regarding concurrency, the call is specified as thread-safe [SWS_CORE_00949]. Within the specialization for references ara::core::Result<T&, E>, the overload [SWS_CORE_00938] exists as a const variant, which returns const T&. This behavior complements the overloads of primary template ara::core::Result for lvalue references [SWS_CORE_00778], const lvalue references [SWS_CORE_00766], and rvalue references [SWS_CORE_00769], as well as the specialization for void [SWS_CORE_00866].

This usage note was generated automatically based on the AUTOSAR specification.
