Enum PickId 

pub enum PickId {
    Skip,
    Block,
    Id(u32),
}

Per-draw-call hitmap directive.

Variants

Skip

Don’t record into the hitmap. Items beneath remain hittable through this primitive. Sensible default for decorative chrome (gridlines, axis ticks, etc.).

Block

Record with id 0 — occludes whatever is beneath in the hitmap, but is itself reported as “no hit”. Useful for opaque panels/backgrounds that should block picks without being interactive themselves.

Id(u32)

Record with the given id. id 0 is reserved internally for “no hit” and Id(0) is treated identically to Block. Ids above 0xFF_FFFF are truncated to 24 bits — the high byte is discarded.
