1//! Implementation of dynamic EIP-712.
2//!
3//! This allows for the encoding of EIP-712 messages without having to know the
4//! types at compile time. This is useful for things like off-chain signing.
5//! It implements the encoding portion of the EIP-712 spec, and does not
6//! contain any of the signing logic.
