Struct Exposure 

pub struct Exposure { /* private fields */ }

What one frame of the draw layer is worth, which depends on how the producer that drew it blends. Both cases are a rate rather than a constant, and for the same reason.

MilkDrop deposits once per rendered frame into a buffer that decays once per rendered frame, so the two are in step by construction. Here the field decays per second (decay is rate-converted like every other MilkDrop factor), which means a 60 Hz display would deposit twice the light per second that a 30 Hz one does into a buffer that fades at the same rate — and the picture would differ with the refresh, which ADR-0019 exists to prevent. rate is how many nominal frames of wall clock this frame is, and both branches of scale convert through it.

Implementations

impl Exposure

pub fn new(dt: f32) -> Self

From this frame’s dt, capped at four nominal frames: a long frame deposits proportionally more light, but a stall cannot deposit an unbounded amount in one go.
