Trait sp_trie::TrieLayout [−]
pub trait TrieLayout {
type Hash: Hasher;
type Codec: NodeCodec;
const USE_EXTENSION: bool;
const ALLOW_EMPTY: bool;
}Expand description
Various re-exports from the trie-db crate.
Trait with definition of trie layout.
Contains all associated trait needed for
a trie definition or implementation.
Associated Types
type Hash: Hasher
type Hash: HasherHasher to use for this trie.
type Codec: NodeCodec
type Codec: NodeCodecCodec to use (needs to match hasher and nibble ops).
Associated Constants
const USE_EXTENSION: bool
const USE_EXTENSION: boolIf 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
const ALLOW_EMPTY: boolIf true, the trie will allow empty values into TrieDBMut
