Struct ManualTime 

pub struct ManualTime { /* private fields */ }

A hand-driven time source for tests, replays and headless runs.

Nothing in the engine can tell it apart from MonotonicTime, which is the point: a deterministic test drives the same code the game does.

Implementations

impl ManualTime

pub const fn new() -> Self

A source sitting at zero.

pub const fn advance(&mut self, delta: Duration)

Moves time forward.

pub fn advance_secs(&mut self, seconds: f64)

Moves time forward by seconds.

Panics

If seconds is negative or not finite.

pub const fn set(&mut self, now: Duration)

Jumps to an absolute timestamp.
