Digest Writer

Status:	Beta
Documentation:	http://docs.rs/digest-writer/

This crate adds io::Write interface for digest::Digest. Which means you can use io::copy, write! macros and other abstractions with digests.

Example:

use std::fs::File;
use std::io::{self, Write};
use sha2::Sha256;
use digest::Writer;

let digest = Writer::new(Sha256::new());
let mut f = File::open("write.rs").unwrap();
io::copy(f, digest).unwrap();
digest.result();
