Trait IntoWriteFn 

pub trait IntoWriteFn<Ts> {
    type WriteFn;

    // Required method
    fn into_write_fn(self) -> Self::WriteFn;
}

A trait used to inference type of write closure wrapper.

This trait used by FmtWriter, ConcatWriter and IoWriter.

Both IntoWriteFn and IntoTryWriteFn traits provides the same wrappers for closures with *const u8, usize, &[u8], &str and String arguments. This variant uses panicking versions for closures with &CStr, CString, and *const c_char arguments, for a “fail fast” approach.

Required Associated Types

type WriteFn

The corresponding write function wrapper.

Required Methods

fn into_write_fn(self) -> Self::WriteFn

Returns the wrapped function.
