//! EIP-712 encoding utilities
|
||
//!
|
||
//! # Specification
|
||
//!
|
||
//! `encode(domainSeparator : 𝔹²⁵⁶, message : 𝕊) = "\x19\x01" ‖ domainSeparator ‖ hashStruct(message)`
|
||
//! - data adheres to 𝕊, a structure defined in the rigorous eip-712
|
||
//! - `\x01` is needed to comply with EIP-191
|
||
//! - `domainSeparator` and `hashStruct` are defined below
|
||
//!
|
||
//! ## A) domainSeparator
|
||
//!
|
||
//! `domainSeparator = hashStruct(eip712Domain)`
|
||
//! <br/>
|
||
//! <br/>
|
||
//! Struct named `EIP712Domain` with the following fields
|
||
//!
|
||
//! - `name: String`
|
||
//! - `version: String`
|
||
//! - `chain_id: U256`,
|
||
//! - `verifying_contract: H160`
|
||
//! - `salt: Option<H256>`
|
||
//!
|
||
//! ## C) hashStruct
|
||
//!
|
||
//! `hashStruct(s : 𝕊) = keccak256(typeHash ‖ encodeData(s))`
|
||
//! <br/>
|
||
//! `typeHash = keccak256(encodeType(typeOf(s)))`
|
||
//!
|
||
//! ### i) encodeType
|
||
//!
|
||
//! - `name ‖ "(" ‖ member₁ ‖ "," ‖ member₂ ‖ "," ‖ … ‖ memberₙ ")"`
|
||
//! - each member is written as `type ‖ " " ‖ name`
|
||
//! - encodings cascade down and are sorted by name
|
||
//!
|
||
//! ### ii) encodeData
|
||
//!
|
||
//! - `enc(value₁) ‖ enc(value₂) ‖ … ‖ enc(valueₙ)`
|
||
//! - each encoded member is 32-byte long
|
||
//!
|
||
//! #### a) atomic
|
||
//!
|
||
//! - `boolean` => `U256`
|
||
//! - `address` => `H160`
|
||
//! - `uint` => sign-extended `U256` in big endian order
|
||
//! - `bytes1:31` => `H@256`
|
||
//!
|
||
//! #### b) dynamic
|
||
//!
|
||
//! - `bytes` => `keccak256(bytes)`
|
||
//! - `string` => `keccak256(string)`
|
||
//!
|
||
//! #### c) referenced
|
||
//!
|
||
//! - `array` => `keccak256(encodeData(array))`
|
||
//! - `struct` => `rec(keccak256(hashStruct(struct)))`
|
||
//!
|
||
//! ## D) Example

//! ### Query
