Struct atomic_linked_list::atomic_map::AtomicMap

pub struct AtomicMap<K, V>where
    K: PartialEq,{ /* private fields */ }

Implementations

impl<K, V> AtomicMap<K, V>where K: PartialEq,

pub const fn new() -> AtomicMap<K, V>

Create a new empty AtomicMap.

Does not perform any allocation until a new node is created.

pub fn insert(&self, key: K, value: V) -> Option<V>

Adds a new key-value pair to the map. If the given key is already present, its corresponding value will be overwritten.

pub fn insert_timeout( &self, key: K, value: V, max_attempts: u64 ) -> Result<Option<V>, V>

Adds a new key-value pair to the map. If the given key is already present, its corresponding value will be overwritten. If it fails to do so atomically after the given number of attempts, it will abort and return Err.

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

Returns a reference to the value matching the given key, if present. Otherwise, returns None.

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

Returns a mutable reference to the value matching the given key, if present. Otherwise, returns None. In order to maintain memory safety (to ensure atomicity), getting a value as mutable requires self (this AtomicMap instance) to be borrowed mutably.

pub fn iter(&self) -> AtomicMapIter<'_, K, V>

Returns a forward iterator through this map.

Formats the value using the given formatter.

impl<K, V> Drop for AtomicMap<K, V>where K: PartialEq,
