Enum deadpool::managed::Hook

pub enum Hook<M: Manager> {
    Fn(Box<dyn Fn(&mut <M as Manager>::Type, &Metrics) -> HookResult<<M as Manager>::Error> + Sync + Send>),
    AsyncFn(Box<dyn for<'a> Fn(&'a mut <M as Manager>::Type, &'a Metrics) -> HookFuture<'a, <M as Manager>::Error> + Sync + Send>),
}

This is supported on crate feature managed only.

Wrapper for hook functions

Variants

Fn(Box<dyn Fn(&mut <M as Manager>::Type, &Metrics) -> HookResult<<M as Manager>::Error> + Sync + Send>)

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

Tuple Fields of Fn

0: Box<dyn Fn(&mut <M as Manager>::Type, &Metrics) -> HookResult<<M as Manager>::Error> + Sync + Send>

AsyncFn(Box<dyn for<'a> Fn(&'a mut <M as Manager>::Type, &'a Metrics) -> HookFuture<'a, <M as Manager>::Error> + Sync + Send>)

Use an async function as a hook

Tuple Fields of AsyncFn

0: Box<dyn for<'a> Fn(&'a mut <M as Manager>::Type, &'a Metrics) -> HookFuture<'a, <M as Manager>::Error> + Sync + Send>
