Struct DepthCounter 

pub struct DepthCounter { /* private fields */ }

Hands out the monotonically increasing depths a frame’s draws are stamped with.

Draws are emitted in paint order, so the counter runs from 0 (back-most) upward and never repeats a value inside one frame. It saturates rather than wrapping: a frame with more than u32::MAX draws would otherwise reuse a depth and let a later draw lose the depth test to an earlier one, and the compiler has no error to report on the frame path for it.

Implementations

impl DepthCounter

pub fn new() -> Self

A counter whose first handed-out depth is 0.

pub fn advance(&mut self) -> u32

The next depth, advancing the counter.

pub fn count(&self) -> u32

How many depths have been handed out.
