Struct TtlMap

pub struct TtlMap<K: Hash + Eq + Clone, V> { /* private fields */ }

A HashMap which enforces a time-to-live of records inserted into it.

This is purely a data structure and does not do its own timekeeping; times are instead passed in as an argument to each method.

Compaction happens automatically when values are read or written. As a consequence of this, even reads require the data structure to be mutable.

Implementations

impl<K: Hash + Eq + Clone, V> TtlMap<K, V>

pub fn new(ttl: Duration) -> Self

pub fn insert(&mut self, key: K, value: V, time: SystemTime)

pub fn get_or_insert_with<F: FnOnce() -> V>( &mut self, key: K, func: F, ) -> &mut V

pub fn get(&mut self, key: &K, time: SystemTime) -> Option<&V>

pub fn get_mut(&mut self, key: &K, time: SystemTime) -> Option<&mut V>
