Struct Timestamp

pub struct Timestamp(/* private fields */);

UTC Timestamp with nanosecond precision, millisecond-precision when serialized to serde (JSON).

A Deref/DerefMut implementation is provided to gain access to the inner PrimitiveDateTime object.

Implementations

impl Timestamp

pub fn to_calendar_date(&self) -> (i32, Month, u8)

Get the year, month, and day.

Like PrimitiveDateTime::to_calendar_date, but optimized for SSE2/AVX2 when available.

assert_eq!(
    Timestamp::from(datetime!(2019-01-01 0:00)).to_calendar_date(),
    (2019, Month::January, 1)
);
