Struct TextStyle 

pub struct TextStyle {
    pub color: Color,
    pub size_px: f32,
    pub align: TextAlign,
    pub wrap: TextWrap,
    pub max_lines: Option<u32>,
    pub family: Option<Arc<str>>,
    pub weight: u16,
    pub selection_color: Option<Color>,
    pub line_height: Option<LineHeightSpec>,
}

Text style record carrying fill color, size, family/weight, alignment, wrap policy, and optional max-line cap. TextContent is stored separately so keystrokes do not bump change detection on these cold fields. Default: near-white at 16px, weight 400, platform sans-serif, left-aligned, no wrap, unbounded lines.

Fields

color: Color

Fill color. Default is Color::rgb(0.92, 0.92, 0.94).

size_px: f32

Font size in logical pixels.

align: TextAlign

Horizontal alignment inside the content rect.

wrap: TextWrap

Wrap policy passed to the shaper.

max_lines: Option<u32>

Hard cap on lines after shaping; None is unbounded.

family: Option<Arc<str>>

CSS font-family fallback chain as authored (comma-separated; the shaper strips quotes and resolves the first available family against the system font database, honouring the CSS generic keywords). None = platform sans-serif. Shared Arc so clones (extract, cache keys) don’t copy the string.

weight: u16

CSS font-weight (1-1000; 400 = normal, 700 = bold).

selection_color: Option<Color>

Selection highlight background (selection-color in CSS; the default skin routes it through the --lumen-selection token) - Qt’s QPalette::Highlight / Slint’s selection-background-color. None falls back to the renderer’s single built-in highlight (crate::render_world::DEFAULT_SELECTION_BG).

The paired caret color and selected-glyph color live on the separate TextInputPaint component so adding them never forces every TextStyle literal to change.

line_height: Option<LineHeightSpec>

CSS line-height. Inherits down the tree like Self::size_px (the IR resolves inheritance before this field is populated). None => DEFAULT_LINE_HEIGHT_MULTIPLIER (line-height: normal), resolved via resolve_line_height.

Trait Implementations

impl Clone for TextStyle

fn clone(&self) -> TextStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for TextStyle

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns [ComponentRelationshipAccessor] required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add [ComponentHook] for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert [ComponentHook] for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard [ComponentHook] for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove [ComponentHook] for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn [ComponentHook] for this Component if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

impl Debug for TextStyle

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

Formats the value using the given formatter.

impl Default for TextStyle

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TextStyle

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