Struct open_feature::provider::NoOpProvider

pub struct NoOpProvider { /* private fields */ }

The default provider that does nothing.

It always returns EvaluationError for all the given flag keys.

Trait Implementations

impl Debug for NoOpProvider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NoOpProvider

fn default() -> Self

Returns the “default value” for a type.

impl FeatureProvider for NoOpProvider

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 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.

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

Resolve given flag_key as a string value.

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

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

Resolve given flag_key as a struct value.

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

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