OccupiedEntry

oxistore_cache::lru

Struct OccupiedEntry 

Source 
pub struct OccupiedEntry<'a, K, V> { /* private fields */ }
Expand description

A handle to an occupied entry in an LruCache.

Implementations§

Source§

impl<'a, K: Eq + Hash + Clone, V> OccupiedEntry<'a, K, V>

Source

pub fn key(&self) -> &K

Return a reference to the entry’s key.

Source

pub fn get(&self) -> &V

Return a reference to the entry’s value without promoting to MRU.

§Panics

Panics if the entry is no longer present (which cannot happen under normal use, since the entry was checked before constructing this handle).

Source

pub fn remove(self) -> V

Remove the entry and return its value.

§Panics

Panics if the entry is no longer present (which cannot happen under normal use).
