Trait LeafHash

pub trait LeafHash:
    Clone
    + Send
    + Sync {
    type Hash: FieldTrait;
    type Leaf: Clone + Send + Sync;

    // Required method
    fn hash_leaf(&self, leaf: &Self::Leaf) -> Result<Self::Hash>;

    // Provided method
    fn hash_leaves(&self, leaves: &[Self::Leaf]) -> Result<Vec<Self::Hash>> { ... }
}

A trait for a Merkle leaf hash function.

Required Associated Types

type Hash: FieldTrait

type Leaf: Clone + Send + Sync

Required Methods

fn hash_leaf(&self, leaf: &Self::Leaf) -> Result<Self::Hash>

Returns the hash of the given leaf node.

Provided Methods

fn hash_leaves(&self, leaves: &[Self::Leaf]) -> Result<Vec<Self::Hash>>

Returns the hash for each leaf node.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
