Implementations

impl TextSystem

pub fn register_text( &mut self, world: &mut World, _visuals: &mut VisualWorld, component: ComponentId, ) -> Vec<SpawnedGlyph>

pub fn measure( text: &str, wrap_at: usize, word_wrap: bool, word_wrap_tokens: &[String], font_size: f32, ) -> (f32, f32)

Pure text measurement — runs wrap logic without spawning any glyphs.

Returns (width_gu, height_gu) in glyph units after applying font size.

wrap_at = 0 disables wrapping.

pub fn layout_position_for_index( text: &str, index: usize, wrap_at: usize, word_wrap: bool, word_wrap_tokens: &[String], font_size: f32, ) -> (f32, f32)

pub fn caret_local_position( text: &str, caret: usize, wrap_at: usize, word_wrap: bool, word_wrap_tokens: &[String], font_size: f32, ) -> (f32, f32)
