Top 23 Rust no-std Projects

  • serde

    Serialization framework for Rust

    Project mention: Cargo workspace crate dedicated to tests (no lib or bin) | reddit.com/r/learnrust | 2023-01-22

    I have been looking at examples on github from famous crates (such as serde), and I found out that under in the test crate manifest there are none of the above ([lib] or [[bin]] section), and I can't seem to figure out how it can build ?

  • Rhai

    Rhai - An embedded scripting language for Rust.

    Project mention: Best language to use as a scripting lang for my rust app | reddit.com/r/rust | 2023-01-13

  • InfluxDB

    Build time-series-based applications quickly and at scale.. InfluxDB is the Time Series Platform where developers build real-time applications for analytics, IoT and cloud-native services. Easy to start, it is available in the cloud or on-premises.

  • cortex-m-rtic

    Real-Time Interrupt-driven Concurrency (RTIC) framework for ARM Cortex-M microcontrollers

    Project mention: eskarp: Custom design using ergogen, 3D printed case, RP2040 with Rust firmware | reddit.com/r/ErgoMechKeyboards | 2023-01-06

    RTIC - RTOS and task scheduling

  • heapless

    Heapless, `static` friendly data structures

    Project mention: """may_dangle""" stabilization | reddit.com/r/rust | 2022-10-26

  • xargo

    The sysroot manager that lets you build and customize `std`

    Project mention: How to fully replace/reimplement std? | reddit.com/r/rust | 2022-05-20

    I think you can use xargo for this with:

  • time

    Simple time handling in Rust (by time-rs)

    Project mention: time: MSRV policy is changing beginning 2023-07-01 to N-2 rustc versions | reddit.com/r/rust | 2022-12-18

  • embedded-graphics

    A no_std graphics library for embedded applications

    Project mention: How to build GUI for custom LCD screen connected to an Arduino Board? | reddit.com/r/rust | 2022-11-15

    Even if one used embedded-graphics, which would't require a line buffer, 8k is probably not enough RAM for the stack of a non-trivial Rust program. At least my even fairly simple RTIC programs that run fine in the 160k of a Feather M4 do not run at all in the 32k of a Feather M0.

  • cortex-m

    Low level access to Cortex-M processors

  • cortex-m-quickstart

    Template to develop bare metal applications for Cortex-M microcontrollers

    Project mention: Weird Autocomplete Behavior with rust-embedded Template | reddit.com/r/rust | 2022-03-03

    This paragraph is to just give context that everything else has been setup correctly. I have installed all prerequisites and can successfully run cargo generate --git https://github.com/rust-embedded/cortex-m-quickstart. I have edited memory.x as mentioned, and .cargo/config.toml to specify my MCU. I then run cargo build, change my debug configuration to Debug (OpenOCD), hit F5 and successfully reach the first breakpoint.

  • governor

    A rate-limiting library for Rust (formerly ratelimit_meter)

  • beef

    Faster, more compact implementation of std::borrow::Cow (by maciejhirsz)

    Project mention: Faster sorting with decorate-sort-undecorate | reddit.com/r/rust | 2023-01-07

    Also of note: https://github.com/maciejhirsz/beef

  • staticvec

    Implements a fixed-capacity stack-allocated Vec alternative backed by an array, using const generics.

    Project mention: Alternative for Vec for variable size arrays in no_std environment? | reddit.com/r/rust | 2022-05-17

    If you're on nightly, I have a crate that I'd say would seem to be exactly what you're looking for.

  • rust-lexical

    Fast numeric to- and from-string conversion routines.

  • ntfs

    An implementation of the NTFS filesystem in a Rust crate, usable from firmware level up to user-mode.

    Project mention: Am I the only one who finds Rust to be centered around Linux? Any Windows devs want to share their experience with Rust? | reddit.com/r/rust | 2022-02-01

    The most exciting windows project I'm following is /u/ColinFinck's NTFS implementation. It's exciting for what it's doing, and exciting for the kinds of GUIs and tools that can be built on top of it

  • scapegoat

    Safe, fallible, embedded-friendly ordered set/map via a scapegoat tree. Validated against BTreeSet/BTreeMap. (by tnballo)

  • gdbstub

    An ergonomic and easy-to-integrate implementation of the GDB Remote Serial Protocol in Rust, with full no_std support.

    Project mention: A fast STM32 embedded system emulator implemented in Rust | reddit.com/r/rust | 2022-07-24

    now integrate gdbstub to support debugging code inside the emulator :)

  • embedded-alloc

    A heap allocator for Cortex-M processors

    Project mention: Help with alloc_cortex_m build | reddit.com/r/rust | 2022-06-02

  • blisp

    A statically typed Lisp like scripting programming language for Rust.

  • pasts

    Minimal and simpler alternative to the futures crate.

    Project mention: `alternator` gives an async function access to data but gives it back on await points | reddit.com/r/rust | 2022-06-14

    This was one of the original ideas behind pasts. I wanted to share data on a single threaded executor without using RefCell, so I created the Join struct api (renamed and redesigned many times). I'm curious what you think of that approach.

  • cast.rs

    Machine scalar casting that meets your expectations

  • wyhash-rs

    wyhash fast portable non-cryptographic hashing algorithm and random number generator in Rust

  • acid_alloc

    Bare-metal allocators.

    Project mention: acid_alloc, a collection of bare-metal allocators | reddit.com/r/rust | 2022-08-22

  • driver-examples

    Rust example programs for many of my hardware device drivers running on STM32F3 Discovery, STM32F103 "Blue Pill", RaspberryPi and micro:bit boards

    Project mention: Rust embedded device driver examples for bluepill, and other boards | news.ycombinator.com | 2022-07-25
