Trait mhash::WriteMultiHash [−] [src]

pub trait WriteMultiHash {
    fn write_multihash(&mut self, multihash: &MultiHash) -> Result<()>;
}

A trait to allow writing a MultiHash to an object.

This is primarily intended to provide support for the io::Write trait, allowing writing a MultiHash to a stream without having to allocate space to store the bytes.

Required Methods

Write the given MultiHash to this object.

Errors

Any errors encountered when writing to the underlying io::Write stream will be propagated out, if that happens an undefined amount of the MultiHash will have already been written to the stream.

Examples

use mhash::{ MultiHash, MultiHashVariant, WriteMultiHash };
let mut buffer = vec![];
let multihash = MultiHash::new(
    MultiHashVariant::Sha1,
    &[0xde, 0xad, 0xbe, 0xef]).unwrap();
buffer.write_multihash(&multihash).unwrap();
assert_eq!(buffer, [0x11, 0x04, 0xde, 0xad, 0xbe, 0xef]);
