Struct AssetCacheKey 

pub struct AssetCacheKey { /* private fields */ }

Cache key for an asset.

Stores the asset key type and the key value as a type-erased Arc<dyn CacheKey>.

Implementations

impl AssetCacheKey

pub fn new<K: CacheKey + 'static>(key: K) -> Self

Create a new asset cache key.

pub fn debug_repr(&self) -> String

Get the debug representation of this key.

pub fn downcast<K: 'static>(&self) -> Option<&K>

Downcast the key to its original type.

pub fn asset_key_type(&self) -> TypeId

Get the asset key type ID.

pub fn key(&self) -> &Arc<dyn CacheKey>

Get a reference to the type-erased key.

pub fn type_name(&self) -> &'static str

Get the type name for this asset key.

Trait Implementations

impl Clone for AssetCacheKey

fn clone(&self) -> AssetCacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssetCacheKey

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

Formats the value using the given formatter.

impl From<AssetCacheKey> for FullCacheKey

fn from(key: AssetCacheKey) -> Self

Converts to this type from the input type.

impl Hash for AssetCacheKey

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AssetCacheKey

fn eq(&self, other: &Self) -> 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.
