Jiff: Datetime library for Rust (github.com)

Article summary

Jiff is a datetime library for Rust that aims to provide high-level datetime primitives with reasonable performance. It supports automatic and seamless integration with the Time Zone Database, DST-aware arithmetic and rounding, and formatting and parsing zone-aware datetimes losslessly. The library is designed to be easy to use and hard to misuse. Jiff is available on crates.io and can be used by adding it to a project's dependencies in Cargo.toml.

Main themes

• Rust datetime library
• Time Zone Database integration
• DST-aware arithmetic
• Named function parameters
• Struct default field values
• Rust language features

What commenters say

• The author of Jiff is also the author of the Rust regex ecosystem, which is a notable achievement.
• Named function parameters would improve the readability of code, but their implementation is controversial and has been postponed.
• Some commenters argue that struct default field values would be a useful feature, allowing for more concise and expressive code.
• Others point out that the current implementation of `parse()` method on strings is based on the `FromStr` trait and is not an example of the extension trait pattern.
• There is a desire for named parameters in Rust, similar to other languages, to improve code readability and usability.
• The implementation of named parameters is complex and would require considering optional, named, and variadic parameters simultaneously.
• Some commenters disagree on the usefulness of named parameters, with some seeing it as a minor issue and others as a significant improvement.
• The Rust language's design and priorities are debated, with some arguing that named parameters are not a high priority feature.
