Struct MockHook

pub struct MockHook { /* private fields */ }

Hook allows application developers to add arbitrary behavior to the flag evaluation lifecycle. They operate similarly to middleware in many web frameworks.

Implementations

impl MockHook

pub fn checkpoint(&mut self)

Validate that all current expectations for all methods have been satisfied, and discard them.

pub fn new() -> Self

Create a new mock object with no expectations.

This method will not be generated if the real struct already has a new method. However, it will be generated if the struct implements a trait with a new method. The trait’s new method can still be called like <MockX as TraitY>::new

impl MockHook

pub fn expect_before(&mut self) -> &mut Expectation

Create an Expectation for mocking the before method

pub fn expect_after(&mut self) -> &mut Expectation

Create an Expectation for mocking the after method

pub fn expect_error(&mut self) -> &mut Expectation

Create an Expectation for mocking the error method

pub fn expect_finally(&mut self) -> &mut Expectation

Create an Expectation for mocking the finally method

Trait Implementations

impl Debug for MockHook

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

Formats the value using the given formatter.

impl Default for MockHook

fn default() -> Self

Returns the “default value” for a type.

impl Hook for MockHook

Hook allows application developers to add arbitrary behavior to the flag evaluation lifecycle. They operate similarly to middleware in many web frameworks.

fn before<'a, 'life0, 'life1, 'async_trait>( &'life0 self, context: &'life1 HookContext<'a>, hints: 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>, details: &'life2 EvaluationDetails<Value>, hints: 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, hints: 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, context: &'life1 HookContext<'a>, evaluation_details: &'life2 EvaluationDetails<Value>, hints: 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.
