Crate lockmap

Source
Expand description

A thread-safe hashmap implementation providing per-key level locking and atomic operations.

§Overview

lockmap provides a concurrent hashmap implementation that allows fine-grained locking at the key level. It uses internal sharding for better performance under high concurrency.

§Features

  • Thread-safe access with per-key locking
  • Entry API for exclusive access to values
  • Efficient concurrent operations through sharding
  • Safe atomic updates

§Examples

use lockmap::LockMap;

let map = LockMap::<String, u32>::new();

// Basic operations
map.set("key1", 42);
assert_eq!(map.get("key1"), Some(42));

// Entry API for exclusive access
{
    let entry = map.entry("key2");
    entry.value.replace(123);
}

Structs§

  • Entry
    An RAII guard providing exclusive access to a key-value pair in the LockMap.
  • LockMap
    A thread-safe hashmap that supports locking entries at the key level.
