Trait trie_db::TrieLayout [−][src]
pub trait TrieLayout {
type Hash: Hasher;
type Codec: NodeCodec<HashOut = <Self::Hash as Hasher>::Out>;
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[src]
Hasher to use for this trie.
type Codec: NodeCodec<HashOut = <Self::Hash as Hasher>::Out>[src]
Codec to use (needs to match hasher and nibble ops).
Associated Constants
const USE_EXTENSION: bool[src]
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[src]
If true, the trie will allow empty values into TrieDBMut
