Rust's (unofficial) extended standard library: simplicity, performance and supply chain security for everyone

Inspired by Go's extensive standard library, we are building Rust's extended standard library to bring simplicity, performance and supply chain security to every Rust developer.

Learn more in the announcement post: https://kerkour.com/stdx

See DESIGN.md for design principles and lessons learned.

Supported Platforms

Tier 1

Tier 1 platforms are extensively checked and tested.

• x86_64 Linux (x86_64-unknown-linux-gnu / x86_64-unknown-linux-musl)
• aarch64 Linux (aarch64-unknown-linux-gnu / aarch64-unknown-linux-musl)
• wasm32 (wasm32-wasip1)
• aarch64 macOS (aarch64-apple-darwin)

Tier 2

Tier 2 platforms are guaranteed to build but may or may not be tested depending on the current hardware availability.

• aarch64 Android (aarch64-linux-android)
• aarch64 iOS (aarch64-apple-ios)
• riscV32imac Bare Metal (riscv32imac-unknown-none-elf)
• armv7E-M Bare metal (thumbv7em-none-eabi)

Tier 3

Tier 3 targets are those which the Rust codebase has support for, but are not built or tested automatically, so they may or may not work.

• Everything else supported by Rust: https://doc.rust-lang.org/stable/rustc/platform-support.html

Usage

To avoid namespace clashes and supply chain risks, we do not use a centralized package repository. Import packages directly from source, for example:

base64 = { git = "https://github.com/rust-stdx/stdx", branch = "main" }
# or to pin a commit
base64 = { git = "https://github.com/rust-stdx/stdx", rev = "1234" }
# or to use Codeberg
base64 = { git = "https://codeberg.org/rust-stdx/stdx", branch = "main" }
# or fork it and use your own mirror
base64 = { git = "https://git.[my-organization].com/[username]/stdx", branch = "main" }

Contrary to what the name may suggest, most packages also support no_std environments by disabling the default std feature, and some also work without alloc by disabling the alloc feature. Look at the documentation of individual packages to learn more.

Other than crates in the beta repository, the main branch is considered stable. Minor breaking changes may happen from time to time, but we will do our best to reduce disruptions.
