Crate zmanim_calculator 

Calculate zmanim (Jewish halachic times) using KosherJava-style concepts and naming.

Typical usage:

• Build a Location.
• Create a ZmanimCalculator with a date and CalculatorConfig.
• Compute times using ready-made definitions from presets (for example, presets::SUNRISE and presets::SUNSET).

ZmanimCalculator::calculate returns Result<DateTime<Utc>, ZmanimError>. In edge cases (for example high latitudes on specific dates), calculations may return an error.

calculate takes &mut self so repeated calculations can reuse intermediate state. If Rust borrow rules are awkward for your call pattern, clone the calculator and use each clone independently.
