Implementations§
source§impl IslamicObservational
impl IslamicObservational
sourcepub fn new_always_calculating() -> Self
pub fn new_always_calculating() -> Self
Construct a new IslamicObservational
without any precomputed calendrical calculations.
This is the only mode currently possible, but once precomputing is available (#3933) there will be additional constructors that load from data providers.
