pub struct UtcOffset { /* private fields */ }
Expand description

An offset from UTC.

This struct can store values up to ±23:59:59. If you need support outside this range, please file an issue with your use case.

Implementations

A UtcOffset that is UTC.

assert_eq!(UtcOffset::UTC, offset!(UTC));
Run

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));
Run

Create a UtcOffset representing an offset by the number of seconds provided.

assert_eq!(UtcOffset::from_whole_seconds(3_723)?.as_hms(), (1, 2, 3));
Run

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).as_hms(), (1, 2, 3));
assert_eq!(offset!(-1:02:03).as_hms(), (-1, -2, -3));
Run

Obtain the number of whole hours 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_hours(), 1);
assert_eq!(offset!(-1:02:03).whole_hours(), -1);
Run

Obtain the number of whole minutes 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_minutes(), 62);
assert_eq!(offset!(-1:02:03).whole_minutes(), -62);
Run

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);
assert_eq!(offset!(-1:02:03).minutes_past_hour(), -2);
Run

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);
assert_eq!(offset!(-1:02:03).whole_seconds(), -3723);
Run

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);
Run

Check if the offset is exactly UTC.

assert!(!offset!(+1:02:03).is_utc());
assert!(!offset!(-1:02:03).is_utc());
assert!(offset!(UTC).is_utc());
Run

Check if the offset is positive, or east of UTC.

assert!(offset!(+1:02:03).is_positive());
assert!(!offset!(-1:02:03).is_positive());
assert!(!offset!(UTC).is_positive());
Run

Check if the offset is negative, or west of UTC.

assert!(!offset!(+1:02:03).is_negative());
assert!(offset!(-1:02:03).is_negative());
assert!(!offset!(UTC).is_negative());
Run

Format the UtcOffset using the provided format description.

Format the UtcOffset using the provided format description.

let format = format_description::parse("[offset_hour sign:mandatory]:[offset_minute]")?;
assert_eq!(offset!(+1).format(&format)?, "+01:00");
Run

Parse a UtcOffset from the input using the provided format description.

let format = format_description::parse("[offset_hour]:[offset_minute]")?;
assert_eq!(UtcOffset::parse("-03:42", &format)?, offset!(-3:42));
Run
