Trait TimeSource

Source 
pub trait TimeSource<T> {
    // Required method
    fn current_millis(&self) -> T;
}
Expand description

A trait for time sources that return a monotonic or wall-clock timestamp.

This abstraction allows you to plug in a real system clock, a monotonic timer, or a mocked time source in tests.

The timestamp type T is generic (typically u64 or u128), and the unit is expected to be milliseconds relative to a configurable origin.

§Example

use ferroid::TimeSource;

struct FixedTime;
impl TimeSource<u64> for FixedTime {
    fn current_millis(&self) -> u64 {
        1234
    }
}

let time = FixedTime;
assert_eq!(time.current_millis(), 1234);

Required Methods§

Source

fn current_millis(&self) -> T

Returns the current time in milliseconds since the configured epoch.
