Struct TryWriteCStrFn

Source
pub struct TryWriteCStrFn<F, R>(/* private fields */)
where
    F: FnMut(&CStr) -> R;
Expand description

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.
