Struct time::Date

pub struct Date { /* private fields */ }

Expand description

Date in the proleptic Gregorian calendar.

By default, years between ±9999 inclusive are representable. This can be expanded to ±999,999 inclusive by enabling the large-dates crate feature. Doing so has performance implications and introduces some ambiguities when parsing.
