Struct UiTransform 

pub struct UiTransform {
    pub pos: Vec2,
    pub size: Vec2,
    pub z_index: i32,
}

The computed screen-space transform of a UI element. This is populated by the layout system (e.g. UiAgent) after evaluating the taffy tree.

Fields

pos: Vec2

Absolute position of the top-left corner in screen coordinates

size: Vec2

Absolute size in screen coordinates

z_index: i32

The Z-index for rendering order. Higher values are rendered on top.

Implementations

impl UiTransform

pub fn rect(&self) -> (Vec2, Vec2)

Get the bounding rect for this transform

pub fn contains(&self, point: Vec2) -> bool

Check if a point is within this transform’s bounds

Trait Implementations

impl Clone for UiTransform

fn clone(&self) -> UiTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for UiTransform

fn make_column() -> Box<dyn AnyVec>

where Self: Sized,

Creates this component’s empty storage column. Default: an AoS Vec<Self>.

fn push_into_column(self, column: &mut dyn AnyVec)

where Self: Sized,

Appends self as a new row into its column.

fn copy_row_between(src: &dyn AnyVec, src_row: usize, dst: &mut dyn AnyVec)

where Self: Sized,

Clones row src_row from src into dst (used when an entity migrates between pages on a structural change). Both columns are this component’s column type.

fn clone_from_column(column: &dyn AnyVec, row: usize) -> Self

where Self: Sized,

Reads row row of column as an owned value — the uniform by-value access path that works for both AoS (clone the &T) and field-SoA (gather the fields) layouts. Used by World::clone_component, the Soa<T> query, and the serialization recipe.

fn set_in_column(self, column: &mut dyn AnyVec, row: usize)

where Self: Sized,

Overwrites row row of column with self — the uniform by-value write path for both layouts (AoS assigns the slot; field-SoA scatters into the lanes). Used by World::set_component.

impl Debug for UiTransform

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

Formats the value using the given formatter.

impl Default for UiTransform

fn default() -> Self

Returns the “default value” for a type.

impl From<UiTransform> for UiTransform

fn from(t: UiTransform) -> Self

Converts to this type from the input type.

impl From<UiTransform> for UiTransform

fn from(t: UiTransform) -> Self

Converts to this type from the input type.

impl PartialEq for UiTransform

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