Faithful transliteration of a Rust time library ensuring feature parity; delivers comprehensive date/time primitives, parsing/formatting, timezone handling, and source-provenance headers.
This is a Kotlin Multiplatform line-by-line transliteration port of time-rs/time.
Original Project: This port is based on time-rs/time. All design credit and project intent belong to the upstream authors; this repository is a faithful port to Kotlin Multiplatform with no behavioural changes intended.
This is an in-progress port. The goal is feature parity with the upstream Rust crate while providing a native Kotlin Multiplatform API. Every Kotlin file carries a // port-lint: source <path> header naming its upstream Rust counterpart so the AST-distance tool can track provenance.
The text below is reproduced and lightly edited from
https://github.com/time-rs/time. It is the upstream project's own description and remains under the upstream authors' authorship; links have been rewritten to absolute upstream URLs so they continue to resolve from this repository.
Documentation:
time is guaranteed to compile with the latest stable release of Rust in addition to the two prior
minor releases. For example, if the latest stable Rust release is 1.70, then time is guaranteed to
compile with Rust 1.68, 1.69, and 1.70.
The minimum supported Rust version may be increased to one of the aforementioned versions if doing so provides the end user a benefit. However, the minimum supported Rust version may also be bumped to a version four minor releases prior to the most recent stable release if doing so improves code quality or maintainability.
For interoperability with third-party crates, it is guaranteed that there exists a version of that
crate that supports the minimum supported Rust version of time. This does not mean that the latest
version of the third-party crate supports the minimum supported Rust version of time.
Contributions are always welcome! If you have an idea, it's best to float it by me before working on it to ensure no effort is wasted. If there's already an open issue for it, knock yourself out. Internal documentation can be viewed here.
If you have any questions, feel free to use Discussions. Don't hesitate to ask questions — that's what I'm here for!
