Struct custom_print::WriteStrFn

pub struct WriteStrFn<F, R>(_)
 where
    F: FnMut(&str) -> R;

A wrapper for write functions for<R> FnMut(&str) -> R.

It implements WriteStr trait and can be used in conjunction with IntoWriteFn and IntoTryWriteFn traits to simplify type inference.

Implementations

impl<F, R> WriteStrFn<F, R> where
    F: FnMut(&str) -> R, 

pub fn new(closure: F) -> Self

Creates a new WriteStrFn containing the given closure or function.

Trait Implementations

impl<F: Clone, R: Clone> Clone for WriteStrFn<F, R> where
    F: FnMut(&str) -> R, 

fn clone(&self) -> WriteStrFn<F, R>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
