Functional Requirements

Result-Based Error Handling		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Functional satisfies: feat_req__baselibs__core_utilities, feat_req__baselibs__result_library, feat_req__baselibs__safety
The Result library shall provide an error handling mechanism that enables functions to return either successful values or error information without using C++ exceptions.
comp_req__result__error_handling		Component Requirement

Domain-Specific Error Information		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Functional satisfies: feat_req__baselibs__core_utilities, feat_req__baselibs__result_library, feat_req__baselibs__safety
The Result library shall support user-defined error domains and error codes.
comp_req__result__domain_error_information		Component Requirement

Type-Safe Error Handling		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Functional satisfies: feat_req__baselibs__consistent_apis, feat_req__baselibs__safety
The Result library shall enforce compile-time type safety for error handling operations.
comp_req__result__type_safety		Component Requirement

Standard Library Integration		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Functional satisfies: feat_req__baselibs__consistent_apis, feat_req__baselibs__safety
The Result library shall provide conversion utilities to transform Result objects into standard library optional type, with enforced error handling.
comp_req__result__std_integration		Component Requirement

Non-Functional Requirements

Deterministic Behavior		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Non-Functional satisfies: feat_req__baselibs__core_utilities, feat_req__baselibs__safety
The Result library shall provide deterministic behavior with no dynamic memory allocation.

Exception-Free Operation		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Non-Functional satisfies: feat_req__baselibs__core_utilities, feat_req__baselibs__safety
The Result library shall operate without throwing C++ exceptions.

Assumptions of Use (AoU)

Error Domain Implementation		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Functional
The user shall implement error domain classes and error code enumerations according to the library’s interface specification.
aou_req__result__error_domain_implementation		Assumption of Use Requirement

Result Value Handling		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Functional
The user shall check and handle both successful and error states of Result objects before accessing contained values to prevent undefined behavior.
aou_req__result__value_handling		Assumption of Use Requirement

Thread Safety		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Non-Functional
The user shall ensure appropriate synchronization mechanisms when using Result objects in multi-threaded environments, as the library provides no internal thread safety guarantees.
aou_req__result__thread_safety		Assumption of Use Requirement

Resource Lifetime		status: valid security: NO safety: ASIL_B
tags: inspected, baselibs, result_library reqtype: Non-Functional
The user shall ensure that error domain objects and referenced resources remain valid throughout the entire lifetime of any dependent Result or Error objects.
