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 3.5ns flat!

test swap ... bench:         7 ns/iter (+/- 0)

Limitations

libfringe currently doesn't work on anything but 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.
