TextRunCache

ferroui_base::media::text_formatting

Struct TextRunCache 

Source 
pub struct TextRunCache { /* private fields */ }
Expand description

Caches shaped text runs and bidi processing results to avoid redundant shaping when only the paragraph width constraint changes (e.g., between Measure and Arrange).

Uses an inline single-entry store for the common case of a single paragraph, and only promotes to a dictionary when multiple entries are added.

This API is in preview and subject to change without deprecation.

Implementations§

Source§

impl TextRunCache

Source

pub fn new() -> Self

Source

pub fn invalidate(&self)

Source

pub fn invalidate_from(&self, text_source_index: i32)

Invalidates all cached entries at or after the specified text source index.

Source

pub fn dispose(&self)

Releases the cache.
