Struct custom_print::TryWriteCStrFn

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

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

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

Implementations

impl<F, R> TryWriteCStrFn<F, R> where
    F: FnMut(&CStr) -> R, 

pub fn new(closure: F) -> Self

Creates a new TryWriteCStrFn containing the given closure or function.
