Struct StepBudget 

pub struct StepBudget(/* private fields */);

The most simulation steps one frame may execute. Everything beyond it is discarded and reported, never banked.

The budget is the only guard on per-frame work, deliberately. An elapsed-time clamp in front of it was considered and rejected: it only changes how much time is discarded versus reported, destroying the information about how big the hitch was in exchange for a second knob, a second branch, and a second coverage obligation.

Implementations

impl StepBudget

pub const DEFAULT: Self

Five steps — about 83 ms of simulation per frame at 60 Hz.

Whether five is the right number is an open question the first frame-time capture on the reference machine settles, not an argument.

pub const fn new(steps: NonZeroU32) -> Self

pub const fn get(self) -> NonZeroU32
