Enum patricia_trie::TrieKinds

pub enum TrieKinds<'db> {
    Generic(TrieDB<'db>),
    Secure(SecTrieDB<'db>),
    Fat(FatDB<'db>),
}

All different kinds of tries. This is used to prevent a heap allocation for every created trie.

Variants

Generic(TrieDB<'db>)

A generic trie db.

Secure(SecTrieDB<'db>)

A secure trie db.

Fat(FatDB<'db>)

A fat trie db.

Trait Implementations

impl<'db> Trie for TrieKinds<'db>

fn root(&self) -> &H256

Return the root of the trie.

fn is_empty(&self) -> bool

Is the trie empty?

fn contains(&self, key: &[u8]) -> Result<bool>

Does the trie contain a given key?

fn get_with<'a, 'key, Q: Query>(
    &'a self,
    key: &'key [u8],
    query: Q
) -> Result<Option<Q::Item>> where
    'a: 'key, 

Search for the key with the given query parameter. See the docs of the Query trait for more details.

fn iter<'a>(&'a self) -> Result<Box<TrieIterator<Item = TrieItem> + 'a>>

Returns a depth-first iterator over the elements of trie.

fn get<'a, 'key>(&'a self, key: &'key [u8]) -> Result<Option<DBValue>> where
    'a: 'key, 

What is the value of the given key in this trie?
