 From-scratch builds with incremental compilation{{hi:Incremental compilation}} enabled adds about 15–20% overhead compared to disabled. The initial build needs to write out more intermediate state in order for later incremental builds to take advantage of it. In a CI{{hi:CI}} situation, it would be extremely unusual for there to be a later incremental build within the same job. The jobs are not making changes to source code and rebuilding. However, workflows that cache the target directory across runs might be benefiting from incremental compilation.

+`slotmpa` provides three containers with persistent unique keys to access stored values, `SlotMap`, `HopSlotMap` and `DenseSlotMap`. Upon insertion a key is returned that can be used to later access or remove the values. Insertion, deletion and access all take O(1) time with low overhead. Use it to store collections of objects that need stable, safe references but have no clear ownership otherwise, such as game entities or graph nodes. Two secondary maps, `SecondaryMap` and `SparseSecondaryMap` are also provided that map further objects to the keys created by one of the slot maps.

 ## Wgpu
 
 A cross-platform, safe, pure-Rust graphics API: [github.com/gfx-rs/wgpu][c-wgpu-github]⮳.
 It runs natively on Vulkan, Metal, D3D12, and OpenGL; and on top of WebGL2 and WebGPU on wasm. The API is based on the [WebGPU standard][webgpu-website]⮳. It serves as the core of the WebGPU integration in Firefox and Deno.

 pest is a general purpose parser written in Rust with a focus on **accessibility**, **correctness**, and **performance**. It uses [parsing expression grammars (or PEG)][wikipedia-parsing-expression-grammars]⮳ as input, which are similar in spirit to regular expressions, but which offer the enhanced expressivity needed to parse complex languages.
 
 Grammars are saved in separate `.pest` files which are never mixed with procedural code. This results in an always up-to-date formalization of a language that is easy to read and maintain.
