Trait nmt_rs::NamespaceMerkleHasher

pub trait NamespaceMerkleHasher<const NS_ID_SIZE: usize>: MerkleHash {
    // Required methods
    fn with_ignore_max_ns(ignore_max_ns: bool) -> Self;
    fn ignores_max_ns(&self) -> bool;
    fn hash_leaf_with_namespace(
        &self,
        data: &[u8],
        namespace: NamespaceId<NS_ID_SIZE>,
    ) -> <Self as MerkleHash>::Output;
}

An extension of MerkleHash indicating that the hasher is namespace aware. This allows for the creation of namespaced merkle trees and namespaced merkle proofs.

Required Methods

fn with_ignore_max_ns(ignore_max_ns: bool) -> Self

Create a new hasher which ignores the max namespace

fn ignores_max_ns(&self) -> bool

Check whether the hasher ignores the max namespace

fn hash_leaf_with_namespace( &self, data: &[u8], namespace: NamespaceId<NS_ID_SIZE>, ) -> <Self as MerkleHash>::Output

Hash the given data and namespace

Object Safety

This trait is not object safe.
