ccbrown / aarch64-std

implementations of standard library components for bare-metal aarch64

aarch64-std

aarch64-std implements components from the Rust standard library in a way suitable for no_std or bare metal ARM applications.

Design Goals

In order:

1. Run on any aarch64 platform at EL0. Anything from microcontrollers to Zynq UltraScale+ MPSoCs to M1 Macs should just work.
2. Mimic the standard library APIs as closely as possible. For the most part these modules are drop-in replacements for the standard library.
3. Perform as efficiently as possible.

Highlights

• sync
  • Mutex
• thread
  • sleep
  • spawn
    • Uses cooperative green threads.
    • As many cores as you'd like can participate using thread::contribute.
    • Threads yield via the standard thread::yield_now function.
• time
  • Instant

Cargo Features

• "alloc" enables functionality which requires the use of the alloc crate. It's enabled by default, but may be disabled if you don't have an allocator available.
