Announcing Leapfrog, a faster concurrent HashMap

• dashmap

  12 2,709 5.5 Rust

  Blazing fast concurrent HashMap for Rust.

  Dashmap made some api changes compared to the stdlibs hashmap, which leads to some oddities, as highlighted here: https://github.com/xacrimon/dashmap/issues/175

• leapfrog

  3 184 4.4 Rust

  Lock-free concurrent and single-threaded hash map implementations using Leapfrog probing. Currently the highest performance concurrent HashMap in Rust for certain use cases.

  For a personal project I needed a concurrent HashMap, so thought I would port one of the fast C++ hashmaps to Rust., which I have called Leapfrog. The API is similar to the HashMap in the std library, but to improve concurrent performance it is slightly different in places.
