qsv-dateparser

A rust library for parsing date strings in commonly used formats. Parsed date will be returned as chrono's DateTime<Utc>.

This is a fork of Rollie Ma's dateparser, specifically published to support qsv. It supports a subset of date formats supported by dateparser, skipping more obscure formats, primarily for performance. It also adds support for parsing dates in DMY format, with the parse_with_preference function.

It will also be the foundation for replacing the chrono crate, with its long-standing security advisory.
