Trait merkle::Hashable [−] [src]

pub trait Hashable {
    fn update_context(&self, context: &mut Context);
}

The type of values stored in a MerkleTree must implement this trait, in order for them to be able to be fed to a Ring Context when computing the hash of a leaf.

A default instance for types that already implements AsRef<[u8]> is provided.

Example

Here is an example of how to implement Hashable for a type that does not (or cannot) implement AsRef<[u8]>:

impl Hashable for PublicKey {
    fn update_context(&self, context: &mut Context) {
        let bytes: Vec<u8> = self.to_bytes();
        context.update(&bytes);
    }
}

Required Methods

Update the given context with self.

See ring::digest::Context::update for more information.
