Struct DynamicSurfaceCache 

pub struct DynamicSurfaceCache { /* private fields */ }

A cache for dynamic surfaces, the content of which changes every frame. The main purpose of this cache is to keep associated GPU buffers alive a long as the surfaces in the cache and thus prevent redundant resource reallocation on every frame. This is very important for dynamic drawing, such as 2D sprites, tile maps, etc.

Implementations

impl DynamicSurfaceCache

pub fn new() -> Self

Creates a new empty cache.

pub fn get_or_create( &mut self, unique_id: u64, layout: &[VertexAttributeDescriptor], ) -> SurfaceResource

Tries to get an existing surface from the cache using its unique id or creates a new one and returns it.

pub fn clear(&mut self)

Clears the surfaces in the cache, does not clear the cache itself.

Trait Implementations

impl Default for DynamicSurfaceCache

fn default() -> DynamicSurfaceCache

Returns the “default value” for a type.
