Crate melin_types 

Shared trading domain primitives (Side, TimeInForce, AccountId, …) and little-endian encoding helpers, extracted from melin-trading so that crates which only need the wire-level data model (the protocol codec, market-data publishers, gateway crates) don’t transitively pull the trading engine glue.

melin-trading re-exports both modules for backwards compatibility, so existing melin_trading::types::* / melin_trading::le::* paths keep resolving while consumers migrate.

Modules

le

Shared little-endian encoding/decoding helpers.

types

Shared trading types: the wire-level data model used by the matching engine, the protocol codec, and the no-op transport binary.
