==== Standard library ====
[[File:Rust standard libraries.svg|thumb|A diagram of the dependencies between the standard library modules of Rust.]]
The Rust [[standard library]] defines and implements many widely used custom data types, including core data structures such as {{rust|Vec}}, {{rust|Option}}, and {{rust|HashMap}}, as well as [[smart pointer]] types. Rust also provides a way to exclude most of the standard library using the attribute {{rust|#![no_std]}}, for applications such as embedded devices. Internally, the standard library is divided into three parts, {{rust|core}}, {{rust|alloc}}, and {{rust|std}}, where {{rust|std}} and {{rust|alloc}} are excluded by {{rust|#![no_std]}}.{{sfn|Gjengset|2021|pp=213-215}}
