Trait Implementations

source

impl Clone for AllowEmptyLayout

source

fn clone(&self) -> AllowEmptyLayout

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Default for AllowEmptyLayout

source

fn default() -> AllowEmptyLayout

Returns the “default value” for a type. Read more

source

impl TrieLayout for AllowEmptyLayout

source

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. Read more

source

const ALLOW_EMPTY: bool = true

If true, the trie will allow empty values into TrieDBMut

source

const MAX_INLINE_VALUE: Option<u32> = None

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

type Hash = KeccakHasher

Hasher to use for this trie.

type Codec = ReferenceNodeCodec<KeccakHasher>

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