✨ feat(mq-lang): add uuid, uuid_v4, and uuid_v7 builtin functions#1965
Merged
Conversation
Adds random UUID generation. `uuid`/`uuid_v4` produce RFC 4122 version 4 UUIDs; `uuid_v7` produces RFC 9562 version 7 (time-ordered, sortable) UUIDs, useful for database primary keys and log IDs. Randomness is delegated to the `rand` crate (OS-seeded via `getrandom`) through a small internal `random` module, rather than a hand-rolled generator, so output isn't predictable from call time. wasm32 support is wired up via getrandom's `wasm_js` feature, verified against both mq-lang and mq-wasm with `cargo check --target wasm32-unknown-unknown`.
Replace the hand-rolled RFC 4122/9562 byte-formatting and version/variant bit-twiddling with the `uuid` crate's `Uuid::new_v4`/`Uuid::now_v7`. Drops the now-unused internal `random` module and its `rand` dependency; the `uuid` crate sources its own CSPRNG (via getrandom on native, and the `js` feature backed by wasm-bindgen on wasm32-unknown-unknown).
