Struct TextCache

pub struct TextCache {
    pub string_cache: FastHashMap<TextId, Words>,
}

Cache for accessing large amounts of text

Fields

string_cache: FastHashMap<TextId, Words>

Mapping from the TextID to the actual, UTF-8 String

This is stored outside of the actual glyph calculation, because usually you don’t need the string, except for rebuilding a cached string (for example, when the font is changed)

Implementations

pub fn add_text(&mut self, words: Words) -> TextId

pub fn delete_text(&mut self, id: TextId)

Removes a string from the string cache, but not the layouted text cache

pub fn clear_all_texts(&mut self)
