Crate fmt2io

Have you ever implemented a nice algorithm that generically uses fmt::Write only to find out it doesn’t work with io::Write? Worry no more - this is the solution!

This crate provides a simple write function which takes your io::Writer, converts it to fmt::Writer and provides it to your closure. This way, you can easily bridge the two traits and have truly generic code.

Example

let mut out = Vec::new();

use std::fmt::Write;

fmt2io::write(&mut out, |writer| write!(writer, "Hello world!")).unwrap();
assert_eq!(out, "Hello world!".as_bytes());

Structs

A bridge between std::io::Write and std::fmt::Write.

Functions
