impl UtcOffset
impl UtcOffset
pub const UTC: UtcOffset = Self::__from_hms_unchecked(0, 0, 0)
pub const UTC: UtcOffset = Self::__from_hms_unchecked(0, 0, 0)
A UtcOffset that is UTC.
assert_eq!(UtcOffset::UTC, offset!(UTC));pub const fn from_hms(
hours: i8,
minutes: i8,
seconds: i8
) -> Result<UtcOffset, ComponentRange>
pub const fn from_hms(
hours: i8,
minutes: i8,
seconds: i8
) -> Result<UtcOffset, ComponentRange>
Create a UtcOffset representing an offset by the number of hours, minutes, and seconds
provided.
The sign of all three components should match. If they do not, all smaller components will have their signs flipped.
assert_eq!(UtcOffset::from_hms(1, 2, 3)?.as_hms(), (1, 2, 3));
assert_eq!(UtcOffset::from_hms(1, -2, -3)?.as_hms(), (1, 2, 3));pub const fn from_whole_seconds(
seconds: i32
) -> Result<UtcOffset, ComponentRange>
pub const fn from_whole_seconds(
seconds: i32
) -> Result<UtcOffset, ComponentRange>
Create a UtcOffset representing an offset by the number of seconds provided.

pub const fn as_hms(self) -> (i8, i8, i8)
Obtain the UTC offset as its hours, minutes, and seconds. The sign of all three components will always match. A positive value indicates an offset to the east; a negative to the west.

assert_eq!(offset!(-1:02:03).whole_hours(), -1);pub const fn whole_minutes(self) -> i16
pub const fn whole_minutes(self) -> i16

assert_eq!(offset!(-1:02:03).whole_minutes(), -62);pub const fn minutes_past_hour(self) -> i8
pub const fn minutes_past_hour(self) -> i8
Obtain the number of minutes past the hour the offset is from UTC. A positive value indicates an offset to the east; a negative to the west.

assert_eq!(offset!(-1:02:03).minutes_past_hour(), -2);pub const fn whole_seconds(self) -> i32
pub const fn whole_seconds(self) -> i32
Obtain the number of whole seconds the offset is from UTC. A positive value indicates an offset to the east; a negative to the west.

assert_eq!(offset!(-1:02:03).whole_seconds(), -3723);pub const fn seconds_past_minute(self) -> i8
pub const fn seconds_past_minute(self) -> i8
Obtain the number of seconds past the minute the offset is from UTC. A positive value indicates an offset to the east; a negative to the west.
assert_eq!(offset!(+1:02:03).seconds_past_minute(), 3);
assert_eq!(offset!(-1:02:03).seconds_past_minute(), -3);pub const fn is_utc(self) -> bool
pub const fn is_utc(self) -> bool
Check if the offset is exactly UTC.
