Trait StaticRefFunction

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

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

    // Provided methods
    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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<'a, T, F, R> StaticRefFunction<'a, F, T> for F

where F: Fn(T) -> R,

type Output = R
