Rust hashbrown

The Rust compiler uses hash tables heavily, and the choice of hash function used for these hash tables makes a big difference to the compiler’s speed. By default, Rust hash tables use Siphash 1-3, a hash function that is high quality but fairly slow. In contrast, the Rust compiler uses as hash function called FxHasher, which is surprisingly ...

Rust hashbrown. Apr 25, 2019 · Upgrade to rustc 1.36.0-nightly (e305df184 2019-04-24) This includes a `size_of` regression for a few DOM types, due to rust-lang/rust#58623 which replaces the implementation of `HashMap` in the standard library to Hashbrown. Although `size_of<HashMap>` grows, it’s not obvious how total memory usage is going to be impacted: Hashbrown only has ...

Immutable data structures are data structures which can be copied and modified efficiently without altering the original. The most uncomplicated example of this is the venerable cons list. This crate offers a selection of more modern and flexible data structures with similar properties, tuned for the needs of Rust developers.

Aug 29, 2023 · 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>> .
