• Feature Name: pattern_types
• Start Date: (fill me in with today's date, YYYY-MM-DD)
• RFC PR: rust-lang/rfcs#0000
• Rust Issue: rust-lang/rust#0000

Summary

This RFC introduces pattern types, which are subtypes of matchable types that are statically restricted to a subset of the variants of the original type.

Let's list here crates that enhance Rust as a language.

It not "batteries" like in stdx, but Rust-specific crates for workarounds for various missing features and experimental ideals from non-accepted/postponed RFCs, or just hacky tricks.

The list is supposed to contain (mostly) crates that are internal to Rust, not ones for making Rust deal with "external world" like other languages bindings, file formats, protocols and so on.

Primary focus should be on crates that are not easy to find by conventional means (e.g. no algorithm name, format or protocol to search for).

Note that quality of the listed crates may vary from proof-of-concept to stable-and-widely-used.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).
