Struct whatwg_datetime::TimeZoneOffset

pub struct TimeZoneOffset { /* private fields */ }

A time-zone offset, with a signed number of hours and minutes.

Examples

use whatwg_datetime::{parse_timezone_offset, TimeZoneOffset};

assert_eq!(parse_timezone_offset("-07:00"), TimeZoneOffset::new_opt(-7, 0));

Implementations

impl TimeZoneOffset

pub fn new_opt(hours: i32, minutes: i32) -> Option<Self>

Creates a new TimeZoneOffset from a signed number of hours and minutes.

This asserts that:

• hours are in between -23 and 23, inclusive,
• minutes are in between 0 and 59, inclusive

Examples

use whatwg_datetime::TimeZoneOffset;

assert!(TimeZoneOffset::new_opt(-7, 0).is_some());
assert!(TimeZoneOffset::new_opt(23, 59).is_some());
assert!(TimeZoneOffset::new_opt(24, 0).is_none()); // Hours must be between [-23, 23]
assert!(TimeZoneOffset::new_opt(1, 60).is_none()); // Minutes must be between [0, 59]

pub const fn minute(&self) -> i32

A minute component. This is a number from 0 to 59, inclusive.

Examples

use whatwg_datetime::TimeZoneOffset;

let tz_offset = TimeZoneOffset::new_opt(-7, 0).unwrap();
assert_eq!(tz_offset.minute(), 0);

pub const fn hour(&self) -> i32

A hour component. This is a number from -23 to 23, inclusive.

Examples

use whatwg_datetime::TimeZoneOffset;

let tz_offset = TimeZoneOffset::new_opt(-7, 0).unwrap();
assert_eq!(tz_offset.hour(), -7);

Trait Implementations

impl Clone for TimeZoneOffset

fn clone(&self) -> TimeZoneOffset

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TimeZoneOffset

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<TimeZoneOffset> for TimeZoneOffset

fn eq(&self, other: &TimeZoneOffset) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
