Enum Hook

pub enum Hook<M: Connector> {
    Fn(Box<dyn Fn(&mut <M as Connector>::Connection, &Metrics) -> HookResult<<M as Connector>::Error>>),
    AsyncFn(Box<dyn for<'a> Fn(&'a mut <M as Connector>::Connection, &'a Metrics) -> HookFuture<'a, <M as Connector>::Error>>),
}

Wrapper for hook functions

Variants

Fn(Box<dyn Fn(&mut <M as Connector>::Connection, &Metrics) -> HookResult<<M as Connector>::Error>>)

Use a plain function (non-async) as a hook

AsyncFn(Box<dyn for<'a> Fn(&'a mut <M as Connector>::Connection, &'a Metrics) -> HookFuture<'a, <M as Connector>::Error>>)

Use an async function as a hook

Implementations

impl<M: Connector> Hook<M>

pub fn sync_fn( f: impl Fn(&mut M::Connection, &Metrics) -> HookResult<M::Error> + 'static, ) -> Self

Create Hook from sync function

pub fn async_fn( f: impl for<'a> Fn(&'a mut M::Connection, &'a Metrics) -> HookFuture<'a, M::Error> + 'static, ) -> Self
