Struct boulder::Time

pub struct Time<T: TimeZone> { /* private fields */ }

Increasing timestamps.

Each output is a DateTime, which is separated from the previous value by a fixed Duration.

Example:

use boulder::{Generator, Time};
use chrono::{DateTime, Duration};

let mut g = Time::new(DateTime::parse_from_rfc2822("Wed, 18 May 2022 15:16:00 GMT").unwrap(), Duration::days(1));
assert_eq!(g.generate(), DateTime::parse_from_rfc2822("Wed, 18 May 2022 15:16:00 GMT").unwrap());
assert_eq!(g.generate(), DateTime::parse_from_rfc2822("Thu, 19 May 2022 15:16:00 GMT").unwrap());
assert_eq!(g.generate(), DateTime::parse_from_rfc2822("Fri, 20 May 2022 15:16:00 GMT").unwrap());

Implementations

impl<T: TimeZone> Time<T>

pub fn new(start: DateTime<T>, step: Duration) -> Self

Create a new Time generator.

Here

• start is the first DateTime in the sequence.

• step is the Duration separating any two adjacent times in the sequence.

Example:

use boulder::{Generator, Time};
use chrono::{DateTime, Duration};

let mut g = Time::new(
    DateTime::parse_from_rfc3339("2022-03-31T17:40:00+01:00").unwrap(),
    Duration::hours(1)
);
let t = g.generate();
assert_eq!(t, DateTime::parse_from_rfc3339("2022-03-31T17:40:00+01:00").unwrap());
let t = g.generate();
assert_eq!(t, DateTime::parse_from_rfc3339("2022-03-31T18:40:00+01:00").unwrap());
let t = g.generate();
assert_eq!(t, DateTime::parse_from_rfc3339("2022-03-31T19:40:00+01:00").unwrap());
