pub enum TrieKinds<'db, 'cache, L: TrieLayout> {
Generic(TrieDB<'db, 'cache, L>),
Secure(SecTrieDB<'db, 'cache, L>),

}Expand description
All different kinds of tries. This is used to prevent a heap allocation for every created trie.
Variants
Generic(TrieDB<'db, 'cache, L>)
A generic trie db.
Secure(SecTrieDB<'db, 'cache, L>)
A secure trie db.
Fat(FatDB<'db, 'cache, L>)
A fat trie db.

impl<'db, 'cache, L: TrieLayout> Trie<L> for TrieKinds<'db, 'cache, L>
sourcefn contains(&self, key: &[u8]) -> Result<bool, TrieHash<L>, CError<L>>
fn contains(&self, key: &[u8]) -> Result<bool, TrieHash<L>, CError<L>>
Does the trie contain a given key?
sourcefn get_hash(
&self,
key: &[u8]
) -> Result<Option<TrieHash<L>>, TrieHash<L>, CError<L>>
fn get_hash(
&self,
key: &[u8]
) -> Result<Option<TrieHash<L>>, TrieHash<L>, CError<L>>
Returns the hash of the value for key.
