Struct ClipState 

pub struct ClipState {
    pub reference: u32,
    pub role: ClipRole,
}

The stencil state one draw needs.

reference is what the stencil is compared against, stated directly rather than derived from a nesting depth, so the HAL needs no notion of a clip stack: a narrowing draw compares against the depth it is leaving and a widening draw against the one it is leaving behind, and which is which is the recorder’s business.

Fields

reference: u32

role: ClipRole

Implementations

impl ClipState

pub const UNCLIPPED: Self

Content outside any clip, which needs no stencil at all.

pub const fn content(reference: u32) -> Self

pub const fn narrow(from: u32) -> Self

pub const fn widen(from: u32) -> Self

pub const fn needs_stencil(self) -> bool

Whether this needs a stencil attachment to mean anything.
