pub struct TrieDBMutBuilder<'db, L: TrieLayout> { /* private fields */ }
Expand description

A builder for creating a TrieDBMut.

Implementations§

source§

impl<'db, L: TrieLayout> TrieDBMutBuilder<'db, L>

source

pub fn new( db: &'db mut dyn HashDB<L::Hash, DBValue>, root: &'db mut TrieHash<L> ) -> Self

Create a builder for constructing a new trie with the backing database db and empty root.

source

pub fn from_existing( db: &'db mut dyn HashDB<L::Hash, DBValue>, root: &'db mut TrieHash<L> ) -> Self

Create a builder for constructing a new trie with the backing database db and root.

This doesn’t check if root exists in the given db. If root doesn’t exist it will fail when trying to lookup any key.

source

pub fn with_cache(self, cache: &'db mut dyn TrieCache<L::Codec>) -> Self

Use the given cache for the db.

source

pub fn with_optional_cache<'cache: 'db>( self, cache: Option<&'cache mut dyn TrieCache<L::Codec>> ) -> Self

Use the given optional cache for the db.

source

pub fn with_recorder( self, recorder: &'db mut dyn TrieRecorder<TrieHash<L>> ) -> Self

Use the given recorder to record trie accesses.

source

pub fn with_optional_recorder<'recorder: 'db>( self, recorder: Option<&'recorder mut dyn TrieRecorder<TrieHash<L>>> ) -> Self

Use the given optional recorder to record trie accesses.

source

pub fn build(self) -> TrieDBMut<'db, L>

Build the TrieDBMut.
