Struct reference_trie::AllowEmptyLayout

pub struct AllowEmptyLayout;

Trie that allows empty values.

Trait Implementations

impl Clone for AllowEmptyLayout

fn clone(&self) -> AllowEmptyLayout

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for AllowEmptyLayout

fn default() -> AllowEmptyLayout

Returns the “default value” for a type.

impl TrieLayout for AllowEmptyLayout

const USE_EXTENSION: bool = true

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 = true

If true, the trie will allow empty values into TrieDBMut

const MAX_INLINE_VALUE: Option<u32> = None

Threshold above which an external node should be use to store a node value.

type Hash = KeccakHasher

Hasher to use for this trie.

type Codec = ReferenceNodeCodec<KeccakHasher>

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