Enum Rotation 

pub enum Rotation {
    None,
    Quarter,
    Half,
    ThreeQuarter,
}

How the sprite is turned before it reaches the plane.

Reflections are not here. No driver has asked for them, and a flag nobody sets is a branch nobody tests.

Variants

None

Upright.

Quarter

A quarter turn clockwise.

Half

Half a turn.

ThreeQuarter

Three quarters clockwise.

Implementations

impl Rotation

pub const fn drm_mask(self) -> u64

The DRM_MODE_ROTATE_* bit for this rotation.

Restated rather than pulled from a binding: these are UAPI constants, and the whole point of asking is to compare against a plane’s supported mask before deciding whether the hardware can do the turn.

pub const fn swaps_axes(self) -> bool

Whether this rotation exchanges width and height.
