Struct UtcUnixNanos 

pub struct UtcUnixNanos(pub i128);

Unix-epoch nanoseconds in the UTC scale.

Uses i128 to hold the full range of Unix nanoseconds without overflow. Promote from UtcUnixSeconds via .into(), truncate back with to_seconds_floor.

Example

use leap_sec::{UtcUnixSeconds, UtcUnixNanos};

let ns = UtcUnixNanos(1_700_000_000_500_000_000);
assert_eq!(format!("{ns}"), "1700000000500000000 UTC");

// Promote from seconds
let promoted: UtcUnixNanos = UtcUnixSeconds(1_700_000_000).into();
assert_eq!(promoted, UtcUnixNanos(1_700_000_000_000_000_000));

Implementations

impl UtcUnixNanos

pub const fn to_seconds_floor(self) -> UtcUnixSeconds

Truncate to whole seconds, rounding toward negative infinity.

Example

use leap_sec::{UtcUnixSeconds, UtcUnixNanos};

let ns = UtcUnixNanos(1_700_000_000_999_999_999);
assert_eq!(ns.to_seconds_floor(), UtcUnixSeconds(1_700_000_000));

// Negative values floor correctly
assert_eq!(UtcUnixNanos(-1).to_seconds_floor(), UtcUnixSeconds(-1));

Trait Implementations

impl Clone for UtcUnixNanos

fn clone(&self) -> UtcUnixNanos

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UtcUnixNanos

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

Formats the value using the given formatter.

impl Display for UtcUnixNanos

Displays as "{nanoseconds} UTC" (e.g., "1700000000500000000 UTC").

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

Formats the value using the given formatter.

impl From<UtcUnixSeconds> for UtcUnixNanos

Lossless promotion: multiplies by 1,000,000,000.

fn from(s: UtcUnixSeconds) -> Self

Converts to this type from the input type.

impl Hash for UtcUnixNanos

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for UtcUnixNanos

fn cmp(&self, other: &UtcUnixNanos) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for UtcUnixNanos

fn eq(&self, other: &UtcUnixNanos) -> 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.

impl PartialOrd for UtcUnixNanos

fn partial_cmp(&self, other: &UtcUnixNanos) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
