context-rs
This project offers an easy interface to the famous Boost.Context library and thus provides the building blocks for higher-level abstractions, like coroutines, cooperative threads (userland threads) or an equivalent to C# keyword yield in C++.
Usage
To use context
, first add this to your Cargo.toml
:
[dependencies]
context = "3.0"
And then add this to your source files:
extern crate context;
Performance
The performance heavily depends on the architecture and even on the operating system. A context switch itself is usually as fast as a regular function call though and can thus be viewed as one.
To see this for yourself run cargo bench resume
. You can then compare the
results of the resume
benchmarks (which uses Context::resume()
) to the
results of resume_reference_perf
(which uses regular function calls).
