Enum Transform

#[repr(u32)]
pub enum Transform {
    Normal = 0,
    _90 = 1,
    _180 = 2,
    _270 = 3,

transform from framebuffer to output

This describes the transform that a compositor will apply to a surface to compensate for the rotation or mirroring of an output device.

The flipped values correspond to an initial flip around a vertical axis followed by rotation.

The purpose is mainly to allow clients to render accordingly and tell the compositor, so that for fullscreen surfaces, the compositor will still be able to scan out directly from client surfaces.

Variants

Normal = 0

no transform,

_90 = 1

90 degrees counter-clockwise,

_180 = 2

180 degrees counter-clockwise,

_270 = 3

270 degrees counter-clockwise,

Flipped = 4

180 degree flip around a vertical axis,

Flipped90 = 5

flip and rotate 90 degrees counter-clockwise,

Flipped180 = 6

flip and rotate 180 degrees counter-clockwise,

Flipped270 = 7

flip and rotate 270 degrees counter-clockwise,

Implementations

impl Transform

pub fn from_bits(v: u32) -> Option<Self>

pub fn bits(&self) -> u32

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Transform

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Into<Arg> for Transform

fn into(self) -> Arg

Converts this type into the (usually inferred) input type.

impl PartialEq for Transform

fn eq(&self, other: &Transform) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
