Deprecation notice
zantetsu-trainer and zantetsu-ffi are unmaintained and will receive no further updates.
What happened
As part of zantetsu 0.2 (released 2026-04-07), all ML infrastructure was removed in favour of a pure heuristic parser. The training workflow that zantetsu-trainer powered is no longer needed. The FFI bindings in zantetsu-ffi were built around that ML pipeline and have no remaining purpose.
Tombstone versions (0.2.0) with only a deprecation notice have been published for both crates. Version 0.1.4 of both has been yanked on crates.io.
Migration
- If you used
zantetsu-trainer: remove it from your Cargo.toml. There is no replacement.
- If you used
zantetsu-ffi: remove it from your Cargo.toml. There is no replacement.
- If you used zantetsu for filename parsing: switch to
zantetsu 0.2.
