New

Creates a new cache with the specified name, type, factory, load function, and Prometheus scope. It supports in-memory fixed-size caches or Redis-backed caches, optionally wrapped with Prometheus metrics and a marshaler for data serialization.

def New(
    name: string,
    cacheType: Type,
    f: Factory,
    loadFunc: cache.LoadFunction[T],
    scope: promutils.Scope
) - > cache.CacheInterface[T], error

Creates a new cache with the given name and load function.

Parameters

Name	Type	Description
name	string	The name of the cache, used for scoping Prometheus metrics and for namespacing the cache.
cacheType	Type	The type of cache to create, determining the underlying storage mechanism (e.g., in-memory fixed size or Redis).
f	Factory	A factory object providing the necessary components for creating cache stores, such as in-memory and Redis cache implementations.
loadFunc	cache.LoadFunction[T]	An optional function that will be called to load data into the cache if a requested key is not found. If nil, the cache will not be loadable.
scope	promutils.Scope	The Prometheus scope to use for metrics, allowing for hierarchical metric naming.

Returns

Type	Description
cache.CacheInterface[T], error	A new cache instance configured with the specified type, marshaler, and an optional load function, or an error if the cache cannot be created.
