About
This Rust crate is a binding for the sentencepiece unsupervised text tokenizer. The crate documentation is available online.
libsentencepiece dependency
This crate depends on the sentencepiece C++ library. By default,
this dependency is treated as follows:
- If
sentencepiececould be found withpkg-config, the crate will link against the library found throughpkg-config. Warning: dynamic linking only works correctly with sentencepiece 0.1.95 or later, due to a bug in earlier versions. - Otherwise, the crate's build script will do a static build of the
sentencepiecelibrary. This requires thatcmakeis available.
If you wish to override this behavior, the sentencepiece-sys crate
offers two features:
system: always attempt to link to thesentencepiecelibrary found withpkg-config.static: always do a static build of thesentencepiecelibrary and link against that.
Compatibility

- Native code
- Required
- Binds native code: sentencepiece-sys
- Build uses a native toolchain: cc, cmake, pkg-config

Order: strongest tier first, then most downloads, then name, with unmeasured values last. A library counts downloads over 30 days. An app counts binary downloads per release. An app with none counts its crate downloads over 30 days. ML Rust runs this catalogue, so its closest project always gets a row.

Why ListedNo archive, New or Featured rule places it, so it is Listed.
What it lacks for Featured
- It has 8 active dependents and 5 new dependents in 365 days. Featured needs 11 active dependents or 9 new dependents in 365 days. The repository route reads 24 stars, 9 forks and 7 contributors. It needs 4,539 stars, 434 forks and 79 contributors together.
- The check finds no release commit or manifest that ties the crate to the repository.
- Docs are missing: the primary crate publishes no README.
What else the check found
- The last activity is on 26 Jul 2026, 106 days ago. The rules expect an update within 365 days. Dormancy rule
- The oldest outside issue waits 824 days for a reply, past the limit of 270. No maintainer replied in 365 days. Rot signals rule
