Struct LeapSecondsBuilder 

pub struct LeapSecondsBuilder { /* private fields */ }

A builder for constructing custom LeapSeconds tables.

Example

use leap_sec::prelude::*;

let table = LeapSeconds::builder()
    .add(UtcUnixSeconds(63_072_000), 10)   // 1972-01-01
    .add(UtcUnixSeconds(78_796_800), 11)   // 1972-07-01
    .build()
    .unwrap();

let tai = table.utc_to_tai(UtcUnixSeconds(70_000_000)).unwrap();
assert_eq!(tai, TaiSeconds(70_000_010));

Implementations

impl LeapSecondsBuilder

pub const fn new() -> Self

Create a new empty builder.

pub fn add(self, utc: UtcUnixSeconds, tai_minus_utc: i32) -> Self

Add a leap-second entry.

utc is the UTC Unix timestamp at which the offset takes effect. tai_minus_utc is the cumulative TAI−UTC offset from this point forward.

pub const fn expires_at(self, at: UtcUnixSeconds) -> Self

Set an expiration timestamp for the table.

pub fn build(self) -> Result<LeapSeconds, Error>

Build the leap-second table.

Errors

Returns Error::InvalidTable if:

• The table is empty
• Timestamps are not monotonically increasing

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

Performs copy-assignment from source.

impl Debug for LeapSecondsBuilder

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

impl Default for LeapSecondsBuilder

fn default() -> Self

Returns the “default value” for a type.
