Implementations

impl Date

pub const fn try_from_ymd(
    year: i32,
    month: u8,
    day: u8
) -> Result<Date, ComponentRange>

Attempt to create a Date from the year, month, and day.

assert!(Date::try_from_ymd(2019, 1, 1).is_ok());
assert!(Date::try_from_ymd(2019, 12, 31).is_ok());

Returns None if the date is not valid.

assert!(Date::try_from_ymd(2019, 2, 29).is_err()); // 2019 isn't a leap year.

This function is const fn when using rustc >= 1.46.

pub const fn try_from_yo(
    year: i32,
    ordinal: u16
) -> Result<Date, ComponentRange>
