Enum TextureCacheHandle 

pub enum TextureCacheHandle {
    Empty,
    Auto(WeakFreeListHandle<AutoCacheEntryMarker>),
    Manual(WeakFreeListHandle<ManualCacheEntryMarker>),
}

A texture cache handle is a weak reference to a cache entry.

If the handle has not been inserted into the cache yet, or if the entry was previously inserted and then evicted, lookup of the handle will fail, and the cache handle needs to re-upload this item to the texture cache (see request() below).

Variants

Empty

A fresh handle.

Auto(WeakFreeListHandle<AutoCacheEntryMarker>)

A handle for an entry with automatic eviction.

Manual(WeakFreeListHandle<ManualCacheEntryMarker>)

A handle for an entry with manual eviction.

Implementations

impl TextureCacheHandle

pub fn invalid() -> Self

Trait Implementations

impl Clone for TextureCacheHandle

fn clone(&self) -> TextureCacheHandle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TextureCacheHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl MallocSizeOf for TextureCacheHandle

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for TextureCacheHandle

fn eq(&self, other: &TextureCacheHandle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TextureCacheHandle

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
