| # DashMap |
| |
| 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 `std::collections::HashMap` |
| with some slight changes to handle concurrency. |
| |
| DashMap tries to be very simple to use and to be a direct replacement for `RwLock<HashMap<K, V>>`. |
| To accomplish these goals, all methods take `&self` instead of modifying methods taking `&mut self`. |
| This allows you to put a DashMap in an `Arc<T>` and share it between threads while still 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. |

| ## Cargo features |
| |
| - `serde` - Enables serde support. |
| |
| - `raw-api` - Enables the unstable raw-shard api. |
| |
| - `rayon` - Enables rayon support. |
| |
| - `inline` - Enables `inline-more` feature from the `hashbrown` crate. Can lead to better performance, but with the cost of longer compile-time. |
| |
| - `arbitrary` - Enables support for the `arbitrary` crate. |

| ## Contributing |
| |
| DashMap 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. |
