Modules§

Client: The OpenFeature client. Create it through the [OpenFeature] struct.
ClientMetadata: The metadata of OpenFeature client.
EvaluationContext: The evaluation context provides ambient information for the purposes of flag evaluation. Contextual data may be used as the basis for targeting, including rule-based evaluation, overrides for specific subjects, or fractional flag evaluation.
EvaluationDetails: The result of the flag evaluation process, and made available in the detailed flag resolution functions.
EvaluationError: Struct representing error
EvaluationOptions: Contain hooks.
FlagMetadata: A structure which supports definition of arbitrary properties, with keys of type string, and values of type boolean, string, or number.
HookContext: Context for hooks.
HookHints
HookWrapper
LoggingHook: A hook that logs the evaluation lifecycle of a flag. See the spec
MockHook: Hook allows application developers to add arbitrary behavior to the flag evaluation lifecycle. They operate similarly to middleware in many web frameworks.
OpenFeature: THE struct of the OpenFeature API. Access it via the [SINGLETON] instance.
StructValue: Represent a structure value as defined in the spec.

EvaluationContextFieldValue: Value type of evaluation context custom fields.
EvaluationErrorCode: An enumerated error code represented idiomatically in the implementation language.
EvaluationReason: Reason for evaluation.
FlagMetadataValue: Supported values of flag metadata fields.
Type: Supported types of values. spec.
Value: Hold a value in the evaluation result of supported types.
