Documentation

Minimum Supported Rust Version

Requires Rust 1.60 or higher.

Minimum supported Rust version can be changed in the future, but it will be done with a minor version bump.

Controlling parallelism

halo2 currently uses rayon for parallel computation. The RAYON_NUM_THREADS environment variable can be used to set the number of threads.

You can disable rayon by disabling the "multicore" feature. Warning! Halo2 will lose access to parallelism if you disable the "multicore" feature. This will significantly degrade performance.
