Trait HookCallback 

pub trait HookCallback<I>: Send + Sync
where
    I: Send + 'static,
{
    // Required method
    fn call<'a>(
        &'a self,
        input: I,
        context: HookContext,
    ) -> Pin<Box<dyn Future<Output = HookDecision> + Send + 'a>>;
}

Trait for hook callbacks. Each hook kind has its own concrete callback; the trait is parameterised over the input type.

Required Methods

fn call<'a>( &'a self, input: I, context: HookContext, ) -> Pin<Box<dyn Future<Output = HookDecision> + Send + 'a>>

Called when the matching hook fires.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<F, Fut, I> HookCallback<I> for F

where F: Fn(I, HookContext) -> Fut + Send + Sync, Fut: Future<Output = HookDecision> + Send + 'static, I: Send + 'static,
