pub struct LoggingHook { /* private fields */ }

A hook that logs the evaluation lifecycle of a flag. See the spec

Trait Implementations

impl Default for LoggingHook

fn default() -> LoggingHook

Returns the “default value” for a type.

impl Hook for LoggingHook

fn before<'a, 'life0, 'life1, 'async_trait>( &'life0 self, context: &'life1 HookContext<'a>, __arg2: Option<&'a HookHints>, ) -> Pin<Box<dyn Future<Output = Result<Option<EvaluationContext>, EvaluationError>> + Send + 'async_trait>>

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

This method is called before the flag evaluation.

fn after<'a, 'life0, 'life1, 'life2, 'async_trait>( &'life0 self, context: &'life1 HookContext<'a>, value: &'life2 EvaluationDetails<Value>, __arg3: Option<&'a HookHints>, ) -> Pin<Box<dyn Future<Output = Result<(), EvaluationError>> + Send + 'async_trait>>

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

This method is called after the successful flag evaluation.

fn error<'a, 'life0, 'life1, 'life2, 'async_trait>( &'life0 self, context: &'life1 HookContext<'a>, error: &'life2 EvaluationError, __arg3: Option<&'a HookHints>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

This method is called on error during flag evaluation or error in before hook or after hook.

fn finally<'a, 'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _: &'life1 HookContext<'a>, _: &'life2 EvaluationDetails<Value>, __arg3: Option<&'a HookHints>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

This method is called after the flag evaluation, regardless of the result.
