Implementations

impl<'db, L> TrieFactory<L> where
    L: TrieLayout + 'db, [src][−]

pub fn new(spec: TrieSpec, layout: L) -> Self[src][−]

Creates new factory.

pub fn readonly(
    &self,
    db: &'db dyn HashDBRef<L::Hash, DBValue>,
    root: &'db TrieHash<L>
) -> Result<TrieKinds<'db, L>, TrieHash<L>, CError<L>>[src][−]

Create new immutable instance of Trie.

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

[src][−]

Create new mutable instance of Trie.

pub fn from_existing(
    &self,
    db: &'db mut dyn HashDB<L::Hash, DBValue>,
    root: &'db mut TrieHash<L>
) -> Result<Box<dyn TrieMut<L> + 'db>, TrieHash<L>, CError<L>>[src][−]

Create new mutable instance of trie and check for errors.

pub fn is_fat(&self) -> bool[src][−]

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