Trait StaticRefMutFunction

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

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

    // Provided methods
    fn bind(data: &'a mut D) -> RefFnMut<'a, T, Self::Output> { ... }
    fn bind_send(data: &'a mut D) -> RefSendFnMut<'a, T, Self::Output>
       where D: Send { ... }
}

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

Required Associated Types

type Output

Return type of the defined function.

Required Methods

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

Function definition.

Provided Methods

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

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

fn bind_send(data: &'a mut D) -> RefSendFnMut<'a, T, Self::Output>

where D: Send,

A helper function to create a RefSendFnMut 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> StaticRefMutFunction<'a, F, T> for F

where F: FnMut(T) -> R,

type Output = R
