Zoneinfo_rs

NOTE: This crate is experimental and should be considered unstable.

zoneinfo_rs provides basic parsing and compilation of IANA's time zone database zoneinfo files.

use std::path::Path;
use zoneinfo_rs::{ZoneInfoData, ZoneInfoCompiler};
// Below assumes we are in the parent directory of `tzdata`.
let zoneinfo_filepath = Path::new("./tzdata/");
// Parse and then compile the files from the directory.
let parsed_data = ZoneInfoData::from_zoneinfo_directory(zoneinfo_filepath)?;
let _compiled_data = ZoneInfoCompiler::new(parsed_data).build();

Extra notes

Currently, parsing only supports parsing of zoneinfo files and none of the preprocessing typically completed by awk scripts in tzdata.

It is recommended to still use the baseline awk script until preprocessing is supported.
