Trait simple_ref_fn::StaticRefFunction

pub trait StaticRefFunction<'a, D, T> {
    type Output;

    fn call(data: &'a D, arg: T) -> Self::Output;

    fn bind(data: &'a D) -> RefFn<'a, T, Self::Output> { ... }
    fn bind_sync(data: &'a D) -> RefSyncFn<'a, T, Self::Output>
    where
        D: Sync,
    { ... }
}

A trait for defining a static function will be type erased.

Required Associated Types

type Output

Return type of the defined function.

Required Methods

fn call(data: &'a D, arg: T) -> Self::Output

Function definition.

Provided Methods

fn bind(data: &'a D) -> RefFn<'a, T, Self::Output>

A helper function to create a RefFn object with the defined function.

fn bind_sync(data: &'a D) -> RefSyncFn<'a, T, Self::Output>where
    D: Sync,

A helper function to create a RefSyncFn object with the defined function.

Implementors

impl<'a, T, F, R> StaticRefFunction<'a, F, T> for Fwhere
    F: Fn(T) -> R,
