Struct CachedRenderingData

Source
#[repr(C)]
pub struct CachedRenderingData { /* private fields */ }
Expand description

This structure must be present in items that are Rendered and contains information. Used by the backend.

Implementations§

Source§

impl CachedRenderingData

Source

pub fn release<T>(&self, cache: &mut RenderingCache<T>) -> Option<T>

This function can be used to remove an entry from the rendering cache for a given item, if it exists, i.e. if any data was ever cached. This is typically called by the graphics backend’s implementation of the release_item_graphics_cache function.

Source

pub fn get_entry<'a, T>( &self, cache: &'a mut RenderingCache<T>, ) -> Option<&'a mut CachedGraphicsData<T>>

Return the value if it is in the cache
