Enum zng::layout::TransformStyle

#[repr(u8)]
pub enum TransformStyle {
    Flat = 0,
    Preserve3D = 1,
}

Defines if a widget is part of the same 3D space as the parent.

Variants

Flat = 0

Widget is not a part of the 3D space of the parent. If it has 3D children they will be rendered into a flat plane that is placed in the 3D space of the parent.

Preserve3D = 1

Widget is a part of the 3D space of the parent. If it has 3D children they will be positioned relative to siblings in the same space.

Note that some properties require a flat image to work on, in particular all pixel filter properties including opacity. When such a property is set in a widget that is Preserve3D and has both a parent and one child also Preserve3D the filters are ignored and a warning is logged. When the widget is Preserve3D and the parent is not the filters are applied outside the 3D space, when the widget is Preserve3D with all Flat children the filters are applied inside the 3D space.

Trait Implementations

impl Clone for TransformStyle

fn clone(&self) -> TransformStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransformStyle

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

Formats the value using the given formatter.

impl Default for TransformStyle

fn default() -> TransformStyle

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TransformStyle

fn deserialize<__D>( __deserializer: __D, ) -> Result<TransformStyle, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TransformStyle

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TransformStyle

fn eq(&self, other: &TransformStyle) -> 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.

impl PxToWr for TransformStyle

type AsDevice = ()

Self equivalent in webrender::units::DevicePixel units.

type AsWorld = ()

Self equivalent in `webrender::units::WorldPixel units.

type AsLayout = TransformStyle

Self equivalent in webrender::units::LayoutPixel units.

fn to_wr_device(self) -> <TransformStyle as PxToWr>::AsDevice

Returns self in webrender::units::DevicePixel units.

fn to_wr_world(self) -> <TransformStyle as PxToWr>::AsWorld

Returns self in webrender::units::WorldPixel units.

fn to_wr(self) -> <TransformStyle as PxToWr>::AsLayout

Returns self in webrender::units::LayoutPixel units.

impl Serialize for TransformStyle

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
