Implementations§

source§

impl<'a, K: 'a + Borrow<[u8]>, V: 'a> Entry<'a, K, V>

source

pub fn or_insert(self, default: V) -> &'a mut V

Get a mutable reference to a value already in the trie, if it exists - otherwise, insert a given default value, and return a mutable reference to its new location in the trie.

source

pub fn or_insert_with<F: FnOnce() -> V>(self, default: F) -> &'a mut V

Get a mutable reference to a value already in the trie, if it exists - otherwise, call the provided closure to construct a new value, insert it into the trie, and then return a mutable reference to it.

source

pub fn key(&self) -> &K

Get a reference to the key associated with this entry.
