Struct crystalorb::timestamp::Timestamp[][src]

pub struct Timestamp(_);
Expand description

Represents and identifies a simulation instant.

Implementations

See note about transitivity for Timestamp’s Ord implementation.

Find the corresponding timestamp for the current time in seconds.

Modify itself to become the timestamp of the next frame.

Find the corresponding time in seconds for this timestamp. Since timestamps repeat over time, this function returns the time closest to zero. This makes it useful to find the number of seconds between two timestamps.

Example
use crystalorb::timestamp::Timestamp;
use float_cmp::approx_eq;
const TIMESTEP: f64 = 1.0 / 60.0;

// Given two timestamps.
let t1 = Timestamp::default();
let t2 = t1 + 50;

// We can get the seconds between these two timestamps.
let seconds_difference = (t2 - t1).as_seconds(TIMESTEP);
assert!(approx_eq!(f64, seconds_difference, 50.0 / 60.0, ulps=1));

Note: This is technically not transitive, since we are doing wrapped differences. To guarantee transitivity (for example, to use in BTreeMaps), ensure that all values being compared against each other are at most std::i16::MAX length of each other. (Maybe std::i16::MAX is off by one, but it is at least on the conservative side)
