Struct HoursUtc 

pub struct HoursUtc(/* private fields */);

Hours since midnight UTC that can extend beyond a single day.

Used for sunrise/sunset times without the chrono dependency. Values represent hours since midnight UTC (0 UT) for the calculation date:

• Negative values indicate the previous day
• 0.0 to < 24.0 indicates the current day
• ≥ 24.0 indicates the next day

Example

let morning = HoursUtc::from_hours(6.5); // 06:30 current day
let late_evening = HoursUtc::from_hours(23.5); // 23:30 current day
let after_midnight = HoursUtc::from_hours(24.5); // 00:30 next day
let before_midnight_prev = HoursUtc::from_hours(-0.5); // 23:30 previous day

Implementations

impl HoursUtc

pub const fn from_hours(hours: f64) -> Self

Creates a new HoursUtc from hours since midnight UTC.

Values can be negative (previous day) or ≥ 24.0 (next day).

pub const fn hours(&self) -> f64

Gets the raw hours value.

Can be negative (previous day) or ≥ 24.0 (next day).

pub fn day_and_hours(&self) -> (i32, f64)

Gets the day offset (-1, 0, or 1) and normalized hours (0.0 to < 24.0).

Returns

Tuple of (day_offset, hours_in_day) where:

• day_offset: -1 = previous day, 0 = current day, 1 = next day
• hours_in_day: 0.0 to < 24.0

Example

let time = HoursUtc::from_hours(25.5);
let (day_offset, hours) = time.day_and_hours();
assert_eq!(day_offset, 1);
assert!((hours - 1.5).abs() < 1e-10);

Trait Implementations

impl Clone for HoursUtc

fn clone(&self) -> HoursUtc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HoursUtc

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

Formats the value using the given formatter.

impl PartialEq for HoursUtc

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

Tests for self and other values to be equal, and is used by ==.

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

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