Blazingly fast concurrent map in Rust.
DashMap is an implementation of a concurrent associative array/hashmap in Rust.
DashMap tries to implement an easy to use API similar to
with some slight changes to handle concurrency.
DashMap tries to be very simple to use and to be a direct replacement for
To accomplish these all methods take
&self instead modifying methods taking
This allows you to put a DashMap in an
Arc<T> and share it between threads while being able to modify it.
DashMap puts great effort into performance and aims to be as fast as possible. If you have any suggestions or tips do not hesitate to open an issue or a PR.
serde- Enables serde support.
raw-api- Enables the unstable raw-shard api.
rayon- Enables rayon support.
Creating and testing open-source software like DashMap takes up a large portion of my time and comes with costs such as test hardware. Please consider supporting me and everything I make for the public to enable me to continue doing this.
If you want to support me please head over and take a look at my patreon.
DashMap is gladly accepts contributions! Do not hesitate to open issues or PR's.
I will take a look as soon as I have time for it.
That said I do not get paid (yet) to work on open-source. This means that my time is limited and my work here comes after my personal life.
A comprehensive benchmark suite including DashMap can be found here.
