Struct trie_db::TrieFactory

pub struct TrieFactory { /* private fields */ }

Trie factory.

Implementations

impl TrieFactory

pub fn new(spec: TrieSpec) -> Self

Creates new factory.

pub fn readonly<'db, 'cache, L: TrieLayout>( &self, db: &'db dyn HashDBRef<L::Hash, DBValue>, root: &'db TrieHash<L>, ) -> TrieKinds<'db, 'cache, L>

Create new immutable instance of Trie.

pub fn create<'db, L: TrieLayout + 'db>( &self, db: &'db mut dyn HashDB<L::Hash, DBValue>, root: &'db mut TrieHash<L>, ) -> Box<dyn TrieMut<L> + 'db>

Create new mutable instance of Trie.

pub fn from_existing<'db, L: TrieLayout + 'db>( &self, db: &'db mut dyn HashDB<L::Hash, DBValue>, root: &'db mut TrieHash<L>, ) -> Box<dyn TrieMut<L> + 'db>

Create new mutable instance of trie and check for errors.

pub fn is_fat(&self) -> bool

Returns true iff the trie DB is a fat DB (allows enumeration of keys).
