Trait reference_trie::TrieLayout

pub trait TrieLayout where
    <Self::Codec as NodeCodec>::HashOut == <Self::Hash as Hasher>::Out, {
    type Hash: Hasher;
    type Codec: NodeCodec;

    const USE_EXTENSION: bool;
    const ALLOW_EMPTY: bool;
}

Trait with definition of trie layout. Contains all associated trait needed for a trie definition or implementation.

Associated Types

type Hash: Hasher

Hasher to use for this trie.

type Codec: NodeCodec

Codec to use (needs to match hasher and nibble ops).

Associated Constants

const USE_EXTENSION: bool

If true, the trie will use extension nodes and no partial in branch, if false the trie will only use branch and node with partials in both.

const ALLOW_EMPTY: bool

If true, the trie will allow empty values into TrieDBMut
