FullCacheKey

Struct FullCacheKey 

Source
pub struct FullCacheKey { /* private fields */ }
Expand description

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§

Source§

impl FullCacheKey

Source

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

Create a new full cache key for a query.

Source

pub fn debug_repr(&self) -> &str

Get debug representation for error messages.

Source

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.

Source

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.
