Crate kosher_rust 

Rust port of KosherJava for Jewish holidays, halachic times (zmanim), and Torah/Talmud learning schedules (e.g. Daf Yomi, Pirkei Avos). A no_std crate (optional alloc) for Hebrew calendar extensions, location-based zmanim, and limudim calculators.

Modules

Module	Purpose
calendar	Hebrew dates, holidays, parshiyot, month constants, and calendar traits
zmanim	Sunrise, candle lighting, alos, tzeis, and other halachic times
limudim	Daf Yomi, Mishna Yomis, Tehillim, Pirkei Avos, and related daily units

Each module has its own calendar::prelude, zmanim::prelude, or limudim::prelude. Use prelude at the crate root when an application needs more than one area.

See each module’s documentation for focused examples: calendar for holidays and parsha, zmanim for location-based times, limudim for learning schedules.

Features

Feature	Default	Effect
alloc	yes	Zman preset descriptions; without it the crate stays no_std and calculation APIs are unchanged
defmt	no	defmt::Format on calculator, config, location, and error types

Disable default features in Cargo.toml when targeting embedded platforms that cannot use the allocator:
