Crate cow_types 

cow-types — Layer 1 protocol enums and shared types for the CoW Protocol SDK.

This crate defines the protocol-level enums used across the workspace:

Enum	Purpose
OrderKind	Sell / Buy direction
TokenBalance	Erc20 / External / Internal balance source
SigningScheme	Eip712 / EthSign / Eip1271 / PreSign
EcdsaSigningScheme	ECDSA-only subset (Eip712 / EthSign)
PriceQuality	Fast / Optimal / Verified quote hint

Numeric constants (ZERO, ONE, MAX_UINT256, …) live in cow-primitives.

Modules

flags

Bitfield encoding and decoding of order and trade flags.

trade

Trade and swap encoding for CoW Protocol settlements.

Structs

CowHook

OnchainOrderData

On-chain placement metadata for orders submitted directly on-chain (as opposed to the off-chain API).

UnsignedOrder

An unsigned CoW Protocol order ready to be hashed and signed.

Enums

EcdsaSigningScheme

ECDSA-only signing schemes (EIP-712 or EIP-191).

OrderKind

Whether to sell an exact input amount or buy an exact output amount.

PriceQuality

Quote price-quality hint passed to the orderbook.

SigningScheme

Signing scheme for a CoW Protocol order.

TokenBalance

The ERC-20 balance source/destination for sellToken and buyToken.
