python Holidays package in Rust

In beta, feel free to PR.

Usage

NB: This package requires an internet connection at runtime, unless you use the feature offline. Turning that feature on will embed holidays into your compiled artifact and may have size implications.

x86_64 (default-features = true)

// Result<Arc<CountryHolidayMap>, String>
let all_holidays = py_holidays_rs::get_all_holidays(CountryCode::AU); 

// Result<BTreeMap<SubDivision, BTreeMap<chrono::NaiveDate, String>>, String>
let australian_holidays = py_holidays_rs::get_holidays_by_country(CountryCode::AU); 

x86_64 (features = ["offline"])

// Result<Arc<CountryHolidayMap>, String>
let all_holidays = py_holidays_rs::get_all_holidays(CountryCode::AU); 

// Result<BTreeMap<SubDivision, BTreeMap<chrono::NaiveDate, String>>, String>
let australian_holidays = py_holidays_rs::get_holidays_by_country(CountryCode::AU); 

wasm32 (default-features = true)

py_holidays_rs::wasm32::initialise_all_holidays(CountryCode::AU).await; // you must call this somewhere before you call the get_* function, you only need to call it once

py_holidays_rs::wasm32::initialise_holidays_by_country(CountryCode::AU).await; // you must call this somewhere before you call the get_* function, you only need to call it once per country code
