Implementations
impl PrimitiveDateTime
[src]
pub const fn new(date: Date, time: Time) -> Self
[src]
Create a new PrimitiveDateTime
from the provided Date
and Time
.
assert_eq!( PrimitiveDateTime::new(date!(2019-01-01), time!(0:00)), date!(2019-01-01).midnight(), );
pub fn now() -> Self
[src]
This method returns a value that assumes an offset of UTC.
Create a new PrimitiveDateTime
with the current date and time (UTC).
assert!(PrimitiveDateTime::now().year() >= 2019);

Get the Unix timestamp
representing the PrimitiveDateTime
.

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