type_bridge_migration/
lib.rs

1//! Migration specification IR for type-bridge.
2//!
3//! This crate defines the serde contract that Python migration authoring lowers
4//! into, plus pure validation, checksum gates, the transaction-aware planner,
5//! and the async executor that runs each step over a `Database`.
