WriteHasher
Hash the data being written to a writer.
Supports tokio::io::AsyncWrite, futures::io::AsyncWrite, std::io::Write.
Example
extern crate sha2;
use sha2::Sha256;
use write_hasher::WriteHasher;
let mut file = std::fs::File::open("Cargo.toml").unwrap();
let dest = std::io::sink();
let dest = WriteHasher::<Sha256, _>::new(dest);
std::io::copy(&mut file, &mut dest).unwrap();
let hash = dest.finalize();
You can use async functions as well as std functions for this as well.
