libfringe

libfringe is a low-level green threading library for Rust. It's usable in freestanding environments (like kernels), but it can also provide an easy-to-use stack allocator using your operating system's memory mapping facility.

Performance

libfringe does context switches in 2.5ns flat on x86_64!

test swap ... bench:         5 ns/iter (+/- 1)

…and on x86:

test swap ... bench:         5 ns/iter (+/- 1)

Limitations

libfringe currently doesn't work on anything but x86 and x86_64, and is untested on anything but Linux.

Installation

libfringe is a Cargo package. It's not stable software yet, so you'll have to use it as a git dependency. Add this to your Cargo.toml:

[dependencies.fringe]
git = "https://github.com/edef1c/libfringe.git"

Feature flags

libfringe provides several optional features through Cargo's feature flags. Currently, all of them are enabled by default.

valgrind

Valgrind integration. libfringe will register context stacks with Valgrind.

os

Built-in stack allocator using your your operating system's anonymous memory mapping facility. Currently only available for Unix.
