Package: wnpp Severity: wishlist Owner: Leonardo Arias Fonseca <ag...@riseup.net> * Package name : golang-github-cockroachdb-swiss Version : 0.0~git20250624.d6e517c-1 Upstream Author : CockroachDB * URL : https://github.com/cockroachdb/swiss * License : Apache-2.0 Programming Lang: Go Description : Go port of Google's Swiss Table hash table swiss.Map is a Go implementation of Google's Swiss Tables hash table design (https://abseil.io/about/design/swisstables). The Rust version of Swiss Tables (https://github.com/rust-lang/hashbrown) is now the HashMap implementation in the Rust standard library. . A swiss.Map[K,V] maps keys of type K to values of type V, similar to Go's builtin map[K]V type. The primary advantage of swiss.Map over Go's builtin map is performance. swiss.Map has similar or slightly better performance than Go's builtin map for small map sizes, and significantly better performance at large map sizes. The benchmarks where swiss.Map performs worse are due to a fast-path optimization in Go's builtin maps for tiny (6 or fewer element) maps with int32, int64, or string keys, and when growing a tiny map no initial capacity specified. In the latter case, Go's builtin map is sometimes able to place the map and first bucket on the stack avoiding heap allocations entirely. I want to package this library to unblock mev-boost, ITP bug #1107167, and go-ethereum, ITP bug #890541
