Macro dtt_diff 

macro_rules! dtt_diff {
    ($dt1:expr, $dt2:expr, $unit:expr) => { ... };
}

A helper macro to calculate the difference between two DateTime instances.

Parameters

• $dt1:expr: The first DateTime instance, as a string parseable as i64.
• $dt2:expr: The second DateTime instance, as a string parseable as i64.
• $unit:expr: The unit for the difference (seconds, days, etc.).

Returns

Some(i64) containing the absolute difference in the specified unit, or None if either input cannot be parsed as i64.

Example

use dtt::{dtt_diff, dtt_parse};

let dt1 = "1609459200"; // 2021-01-01 00:00:00 UTC
let dt2 = "1609459230"; // 2021-01-01 00:00:30 UTC
let seconds_difference = dtt_diff!(dt1, dt2, 1);
assert_eq!(seconds_difference, Some(30i64));
