Crate libtzfile

This library reads the system timezone information files provided by IANA and returns a Tz struct representing the TZfile fields as described in the man page (http://man7.org/linux/man-pages/man5/tzfile.5.html).

For higher level parsing, see my high-level parsing library.

Here is an example:

 fn main() {
     println!("{:?}", libtzfile::parse("/usr/share/zoneinfo/America/Phoenix").unwrap());
 }

 Tz { tzh_timecnt_data: [-2717643600, -1633273200, -1615132800, -1601823600, -1583683200, -880210800, -820519140, -812653140, -796845540, -84380400, -68659200],
 tzh_timecnt_indices: [2, 1, 2, 1, 2, 3, 2, 3, 2, 1, 2], tzh_typecnt: [Ttinfo { tt_gmtoff: -26898, tt_isdst: 0, tt_abbrind: 0 },
 Ttinfo { tt_gmtoff: -21600, tt_isdst: 1, tt_abbrind: 1 }, Ttinfo { tt_gmtoff: -25200, tt_isdst: 0, tt_abbrind: 2 },
 Ttinfo { tt_gmtoff: -21600, tt_isdst: 1, tt_abbrind: 3 }], tz_abbr: ["LMT", "MDT", "MST", "MWT"] }

The tests (cargo test) are written to match 2020a version of timezone database.

Structs

Ttinfo	a struct containing UTC offset, daylight saving time, abbreviation index
Tz	struct representing the TZfile fields

Enums

TzError

Functions

parse

the tz parameter is the timezone to query, ie. "/usr/share/zoneinfo/Europe/Paris"
