Standards version of the package is outdated. wishlist. However the current hashbrown code assumes the default is always available. We could have it use fixed keys as HashBrown does not guarantee DOS resistance, but the only obvious way to do this is for it to be aHash specific.

Hashbrown's codebase is way above my paygrade, but the general question is: is this just a limitation of the current implementation, or will it never be possible to remove the bound? Naturally, the allocator needs to be Clone , if the collection wants to implement Clone , but does it need to be Clone otherwise?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>> .AHash is a hashing algorithm is intended to be a high performance, (hardware specific), keyed hash function. This can be seen as a DOS resistant alternative to FxHash, or a fast equivalent to SipHash . It provides a high speed hash algorithm, but where the result is not predictable without knowing a Key. This allows it to be used in a HashMap ... Eq is what we call a marker trait: it has no method on its own, it is just a way for the programmer to express that the struct verifies a certain property. You can implement it like this: impl Eq for Application {} Or alternatively, use #[derive(Eq)] on top of the Application declaration. Eq is a trait bound by PartialEq.This means that you can implement it only …Serde is a framework for serializing and deserializing Rust data structures efficiently and generically.

I recently finished a detailed review of hashbrown, which will likely become the new implementation for rust’s std::collections::HashMap.One of the most surprising things I found was in the implementation of insert, which was essentially:The type HashMap<K, V> stores a mapping of keys of type K to values of type V using a hashing function, which determines how it places these keys and values into memory. Many programming languages support this kind of data structure, but they often use a different name, such as hash, map, object, hash table, dictionary, or associative array ...rust-hashbrown Rust port of Google's SwissTable hash map - Rust source code

This package contains library source intended for building other packages which use the "default" feature of the "hashbrown" crate.

Prepare release of v0.14.2At high level it works like this: Search for the element; if found return it (or in case of hashbrown overwrite and return). Otherwise fallthrough. Find the first empty or tombstone slot. If the slot is a tombstone, insert at this location. If the slot is empty and there is capacity available, insert at this location.
