1 //! This crate contains pre-baked ICU4X data, generated by `icu4x-datagen`. The tool
2 //! fetches locale data from CLDR and transforms them into const code in statics that
3 //! ICU4X can load, via databake. `lib.rs` in this crate is manually written, but all
4 //! other code is generated.
6 //! This crate can be regenerated when there's a new CLDR version, though that is unlikely
7 //! to result in changes in most cases (currently this only covers list formatting data, which
8 //! is rather stable). It may need to be regenerated when updating ICU4X versions, especially
9 //! across major versions, in case it fails to compile after an update.
11 //! It must be regenerated when adding new locales to Rust, or if Rust's usage of ICU4X
12 //! grows to need more kinds of data.
14 //! To regenerate the data, run this command:
17 //! icu4x-datagen -W --pretty --fingerprint --use-separate-crates \
18 //! --format mod -l en es fr it ja pt ru tr zh zh-Hans zh-Hant \
19 //! -k list/and@1 fallback/likelysubtags@1 fallback/parents@1 fallback/supplement/co@1 \
20 //! --cldr-tag latest --icuexport-tag latest -o src/data
