Trait stable_hash::StableHasher

pub trait StableHasher {
    type Out;
    type Seq: SequenceNumber;
    type Unordered: UnorderedAggregator<Self::Seq>;
    fn write(&mut self, sequence_number: Self::Seq, bytes: &[u8]);
    fn start_unordered(&mut self) -> Self::Unordered;

}

Like Hasher, but consistent across:

• builds (independent of rustc version or std implementation details)
• platforms (eg: 32 bit & 64 bit, x68 and ARM)
• processes (multiple runs of the same program)
