Implementations

source

impl<'db, H, C> TrieFactory<H, C> where

source

pub fn new(spec: TrieSpec) -> Self

Creates new factory.

source

pub fn readonly(
 &self,
 db: &'db dyn HashDBRef<H, DBValue>,
 root: &'db H::Out
) -> Result<TrieKinds<'db, H, C>, H::Out, <C as NodeCodec<H>>::Error>

Create new immutable instance of Trie.

source

pub fn create(
 &self,
 db: &'db mut dyn HashDB<H, DBValue>,
 root: &'db mut H::Out
) -> Box<dyn TrieMut<H, C> + 'db>

Create new mutable instance of Trie.

source

pub fn from_existing(
 &self,
 db: &'db mut dyn HashDB<H, DBValue>,
 root: &'db mut H::Out
) -> Result<Box<dyn TrieMut<H, C> + 'db>, H::Out, <C as NodeCodec<H>>::Error>

Create new mutable instance of trie and check for errors.

source

pub fn is_fat(&self) -> bool

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