Struct simple_ref_fn::RefSendFnMut

pub struct RefSendFnMut<'a, T, R> { /* private fields */ }

A simple function wrapper that behaves like a &mut (dyn FnMut(T) -> R + Send) type, but does not require a virtual table.

Implementations

impl<'a, T, R> RefSendFnMut<'a, T, R>

pub fn new<F, D>(data: &'a mut D) -> Selfwhere
    F: StaticRefMutFunction<'a, D, T, Output = R> + ?Sized,
    D: Send,

Create a RefSendFnMut object by binding F::call_mut function with data.

pub fn from_fn_mut<F>(f: &'a mut F) -> Selfwhere
    F: FnMut(T) -> R + Send,

Create a RefSendFnMut object from a function reference.

pub fn call_mut(&mut self, arg: T) -> R

Call the wrapped function.

Trait Implementations

impl<'a, F, T, R> From<&'a mut F> for RefSendFnMut<'a, T, R>where
    F: FnMut(T) -> R + Send,

fn from(value: &'a mut F) -> Self

Converts to this type from the input type.
