moka-cht

moka-cht provides a lock-free hash table that supports fully concurrent lookups, insertions, modifications, and deletions. The table may also be concurrently resized to allow more elements to be inserted. moka-cht also provides a segmented hash table using the same lock-free algorithm for increased concurrent write performance.

Usage

Add this to your Cargo.toml:

toml moka-cht = "0.5"

Then in your code:

```rust use moka_cht::HashMap; use std::{sync::Arc, thread};

let map = Arc::new(HashMap::new());

let threads: Vec<_> = (0..16) .map(|i| { let map = map.clone();

    thread::spawn(move || {
        const NUM_INSERTIONS: usize = 64;

        for j in (i * NUM_INSERTIONS)..((i + 1) * NUM_INSERTIONS) {
            map.insert_and(j, j, |_prev| unreachable!());
        }
    })
})
.collect();

let : Vec<_> = threads.intoiter().map(|t| t.join()).collect(); ```
