Struct RestResolver

pub struct RestResolver { /* private fields */ }

REST-based resolver implementing the OpenFeature Remote Evaluation Protocol

Implementations

impl RestResolver

pub fn new(options: &FlagdOptions) -> Self

Creates a new REST resolver with the specified host and port

Arguments

• target - The host and port of the OFREP service, in the format host:port

Returns

A new instance of RestResolver configured to connect to the specified endpoint

Trait Implementations

impl FeatureProvider for RestResolver

fn resolve_bool_value<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, flag_key: &'life1 str, evaluation_context: &'life2 EvaluationContext, ) -> Pin<Box<dyn Future<Output = EvaluationResult<ResolutionDetails<bool>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Returns

The resolved boolean value with metadata, or an error if evaluation fails

fn resolve_string_value<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, flag_key: &'life1 str, evaluation_context: &'life2 EvaluationContext, ) -> Pin<Box<dyn Future<Output = EvaluationResult<ResolutionDetails<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Resolves a string flag value

Arguments

• flag_key - The unique identifier of the flag
• evaluation_context - Context data for flag evaluation

Returns

The resolved string value with metadata, or an error if evaluation fails

fn resolve_float_value<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, flag_key: &'life1 str, evaluation_context: &'life2 EvaluationContext, ) -> Pin<Box<dyn Future<Output = EvaluationResult<ResolutionDetails<f64>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Resolves a float flag value

Arguments

• flag_key - The unique identifier of the flag
• evaluation_context - Context data for flag evaluation

Returns

The resolved float value with metadata, or an error if evaluation fails

fn resolve_int_value<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, flag_key: &'life1 str, evaluation_context: &'life2 EvaluationContext, ) -> Pin<Box<dyn Future<Output = EvaluationResult<ResolutionDetails<i64>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Resolves an integer flag value

Arguments

• flag_key - The unique identifier of the flag
• evaluation_context - Context data for flag evaluation

Returns

The resolved integer value with metadata, or an error if evaluation fails

fn resolve_struct_value<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, flag_key: &'life1 str, evaluation_context: &'life2 EvaluationContext, ) -> Pin<Box<dyn Future<Output = EvaluationResult<ResolutionDetails<StructValue>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Resolves a structured flag value

Arguments

• flag_key - The unique identifier of the flag
• evaluation_context - Context data for flag evaluation

Returns

The resolved structured value with metadata, or an error if evaluation fails. The structured value can contain nested objects, arrays, and primitive types.

fn metadata(&self) -> &ProviderMetadata

The provider interface MUST define a metadata member or accessor, containing a name field or accessor of type string, which identifies the provider implementation.

fn initialize<'life0, 'life1, 'async_trait>( &'life0 mut self, context: &'life1 EvaluationContext, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

The provider MAY define an initialize function which accepts the global evaluation context as an argument and performs initialization logic relevant to the provider.

fn status(&self) -> ProviderStatus

The provider MAY define a status field/accessor which indicates the readiness of the provider, with possible values NOT_READY, READY, or ERROR.

fn hooks(&self) -> &[HookWrapper]

The provider MAY define a hooks field or accessor which returns a list of hooks that the provider supports.
