Struct TextPipeline 

pub struct TextPipeline {
    pub map_handle_to_font_id: HashMap<AssetId<Font>, (ID, Arc<str>)>,
    /* private fields */
}

The TextPipeline is used to layout and render text blocks (see Text/Text2d).

See the crate-level documentation for more information.

Fields

map_handle_to_font_id: HashMap<AssetId<Font>, (ID, Arc<str>)>

Identifies a font ID by its Font Asset.

Implementations

impl TextPipeline

pub fn update_buffer<'a>( &mut self, fonts: &Assets<Font>, text_spans: impl Iterator<Item = (Entity, usize, &'a str, &'a TextFont, Color)>, linebreak: LineBreak, justify: Justify, bounds: TextBounds, scale_factor: f64, computed: &mut ComputedTextBlock, font_system: &mut CosmicFontSystem, ) -> Result<(), TextError>

Utilizes cosmic_text::Buffer to shape and layout text

Negative or 0.0 font sizes will not be laid out.

pub fn queue_text<'a>( &mut self, layout_info: &mut TextLayoutInfo, fonts: &Assets<Font>, text_spans: impl Iterator<Item = (Entity, usize, &'a str, &'a TextFont, Color)>, scale_factor: f64, layout: &TextLayout, bounds: TextBounds, font_atlas_sets: &mut FontAtlasSets, texture_atlases: &mut Assets<TextureAtlasLayout>, textures: &mut Assets<Image>, computed: &mut ComputedTextBlock, font_system: &mut CosmicFontSystem, swash_cache: &mut SwashCache, ) -> Result<(), TextError>

Queues text for rendering

Produces a TextLayoutInfo, containing PositionedGlyphs which contain information for rendering the text.

pub fn create_text_measure<'a>( &mut self, entity: Entity, fonts: &Assets<Font>, text_spans: impl Iterator<Item = (Entity, usize, &'a str, &'a TextFont, Color)>, scale_factor: f64, layout: &TextLayout, computed: &mut ComputedTextBlock, font_system: &mut CosmicFontSystem, ) -> Result<TextMeasureInfo, TextError>

Queues text for measurement

Produces a TextMeasureInfo which can be used by a layout system to measure the text area on demand.

pub fn get_font_id(&self, asset_id: AssetId<Font>) -> Option<ID>

Returns the cosmic_text::fontdb::ID for a given Font asset.
