Struct FullCacheKey 

pub struct FullCacheKey { /* private fields */ }

Full cache key that includes query type information.

This prevents collisions between different query types that might have the same CacheKey type (e.g., both use u32).

This type is used internally for dependency tracking, but is also exposed for error reporting and future GC functionality.

Implementations

impl FullCacheKey

pub fn new<Q: 'static, K: Key>(key: &K) -> Self

Create a new full cache key for a query.

pub fn debug_repr(&self) -> &str

Get debug representation for error messages.

pub fn query_set_sentinel<Q: 'static>() -> Self

Create a sentinel key representing “all queries of type Q”.

This is used by list_queries to track dependencies on the set of queries, rather than individual query values.

pub fn asset_key_set_sentinel<K: 'static>() -> Self

Create a sentinel key representing “all asset keys of type K”.

This is used by list_asset_keys to track dependencies on the set of asset keys, rather than individual asset values.

Trait Implementations

impl Clone for FullCacheKey

fn clone(&self) -> FullCacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FullCacheKey

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

Formats the value using the given formatter.

impl Hash for FullCacheKey

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 FullCacheKey

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.
