Struct StackEntry 

#[non_exhaustive]
pub struct StackEntry<'a> {
    pub plane: &'a PlaneCapabilities,
    pub requested: Option<u64>,
    pub written: Option<u64>,
    pub below_ties: bool,
}

One armed plane in a frame’s stack.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

plane: &'a PlaneCapabilities

The plane.

requested: Option<u64>

The zpos its layer requests.

written: Option<u64>

The zpos to write, filled by stack_zpos.

below_ties: bool

Stack under the other entries requesting the same zpos, whatever the plane ids: the composition canvas’s slot under the placed layer that must cover it (drm-cxx 07226e4).

Implementations
