Compact Temporal Notation (Provisional)

Motivation

I write a lot, a lot of personal journals in a plain text. They contain a lot of dates and times, many of them should be ideally tracked automatically (like, if I've written "15:00 tomorrow" some software ought to alarm at that time), so they should be written in a consistent manner. So far I've used ISO 8601 date and time format (e.g. 2020-09-05 or 11:30) and a bunch of natural extensions (e.g. tomorrow, last Sun).

And folks, it's verbose or often ambiguous to other plain text! For example I tend to schedule things in a multiple of hours so :00 is not necessary, but a single number 15 would be less recognizable as hours. Many systems will helpfully try to recognize at 15 or 3pm, but how would you know that at 15 is not a part of at 15 km/h or similar? Also my journals are in Korean anyway, and such workarounds tend to not work well crosslingually. How about the intervals like 15:00 thru 18:30? ISO 8601 interval 15:00/18:30 would be particularly problematic because a

// This is a simple typing game where you have lots of short English words to
// quickly type before a timer runs out. Perhaps most surprisingly, the game
// seems to have an access to lots of real English words (1,903 to be exact).

C11 standard library to Rust standard library (as of 2014-07-19 nightly)

As a response to Issue #15753. Not yet complete.

Some notes:

  • All Rust translations assume the crate root (so the reference to std is freely available). The use of any other crates is noted.
  • Every string or vector argument is assumed to be a slice (&str or &[T]). Otherwise you need to convert String or Vec<T> to a slice with .as_slice() method.

<assert.h>

  • assert(cond): assert!(cond) macro. Note that it's always enabled; if you need to selectively disable the assertions, use debug_assert!(cond) macro.
