I wouldn't be surprised to see the Rust ecosystem eventually move to Temporal's api, given v8 (Chrome) adopted Boa's rust implementation temporal_rs (https://docs.rs/temporal_rs/latest/temporal_rs/), see burntsushi's arguments for the need of a better datetime handling library in Rust (https://github.com/BurntSushi/jiff/blob/master/DESIGN.md#why...). I'm not sure his jiff create will be the one, i think temporal_rs has become the authoritative implementation.
