);

pub fn now() -> Self[src]

👎 Deprecated since 0.2.7:

This method returns a value that assumes an offset of UTC.

    PrimitiveDateTime::unix_epoch()
);

);

pub fn timestamp(self) -> i64[src]

👎 Deprecated since 0.2.7:

This method assumes an offset of UTC.

Get the Unix timestamp representing the PrimitiveDateTime.

pub const fn using_offset(self, offset: UtcOffset) -> OffsetDateTime[src]

👎 Deprecated since 0.2.7:

Due to behavior not clear by its name alone, it is preferred to use .assume_utc().to_offset(offset). This has the same behavior and can be used in const contexts.

Assuming that the existing PrimitiveDateTime represents a moment in the UTC, return an OffsetDateTime with the provided UtcOffset.

assert_eq!(
    date!(2019-01-01).midnight().using_offset(offset!(UTC)).unix_timestamp(),
    1_546_300_800,
);
assert_eq!(
    date!(2019-01-01).midnight().using_offset(offset!(-1)).unix_timestamp(),
    1_546_300_800,
);

This function is the same as calling .assume_utc().to_offset(offset).

pub fn assume_offset(self, offset: UtcOffset) -> OffsetDateTime[src]

Assuming that the existing PrimitiveDateTime represents a moment in the provided UtcOffset, return an OffsetDateTime.

assert_eq!(
    date!(2019-01-01).midnight().assume_offset(offset!(UTC)).unix_timestamp(),
    1_546_300_800,
);
assert_eq!(
    date!(2019-01-01).midnight().assume_offset(offset!(-1)).unix_timestamp(),
    1_546_304_400,
);

pub const fn assume_utc(self) -> OffsetDateTime[src]

Assuming that the existing PrimitiveDateTime represents a moment in the UTC, return an OffsetDateTime.

assert_eq!(
    date!(2019-01-01).midnight().assume_utc().unix_timestamp(),
    1_546_300_800,
);

This function is the same as calling .assume_offset(offset!(UTC)), except it is usable in const contexts.

);

pub fn lazy_format(self, format: impl AsRef<str>) -> impl Display[src]

Format the PrimitiveDateTime using the provided string.

assert_eq!(
    date!(2019-01-02).midnight().lazy_format("%F %r").to_string(),
    "2019-01-02 12:00:00 am"
);

pub fn parse(s: impl AsRef<str>, format: impl AsRef<str>) -> Result<Self, Error>[src]

Attempt to parse a PrimitiveDateTime using the provided string.

assert_eq!(
    PrimitiveDateTime::parse("2019-01-02 00:00:00", "%F %T"),
    Ok(date!(2019-01-02).midnight()),
);
assert_eq!(
    PrimitiveDateTime::parse("2019-002 23:59:59", "%Y-%j %T"),
    Ok(date!(2019-002).with_time(time!(23:59:59)))
);
assert_eq!(
    PrimitiveDateTime::parse("2019-W01-3 12:00:00 pm", "%G-W%V-%u %r"),
    Ok(date!(2019-W01-3).with_time(time!(12:00))),
);
