Struct custom_print::TryWriteCCharPtrFn

pub struct TryWriteCCharPtrFn<F, R>(_)
 where
    F: FnMut(*const c_char) -> R;

A wrapper for write functions for<R> FnMut(*const c_char) -> R.

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

Implementations

impl<F, R> TryWriteCCharPtrFn<F, R> where
    F: FnMut(*const c_char) -> R, 

pub fn new(closure: F) -> Self

Creates a new TryWriteCCharPtrFn containing the given closure or function.
