Crate cow_weiroll 

cow-weiroll — Layer 2 Weiroll script builder for the CoW Protocol SDK.

Weiroll is a minimal VM for chaining arbitrary EVM calls into a single transaction. This crate provides the Rust types for building Weiroll scripts and encoding them as execute(bytes32[],bytes[]) calldata targeting the canonical Weiroll executor contract.
