Requires Rust 1.65.0 or higher.

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

halo2_proofs currently uses rayon for parallel computation. The RAYON_NUM_THREADS environment variable can be used to set the number of threads.

When compiling to WASM-targets, notice that since version 1.7, rayon will fallback automatically (with no need to handle features) to require getrandom in order to be able to work. For more info related to WASM-compilation.
