Package: effect
Module: ScopedCache

ScopedCache.make

Creates a ScopedCache with a fixed time-to-live for every lookup result.

When to use

Use to create a scoped cache when every cached lookup result should share the same lifetime.

Details

This is the constant-TTL variant of makeWith: values are acquired by the lookup effect in per-entry scopes, capacity can evict older entries, and entry scopes are closed when entries expire, are invalidated, are evicted, or when the cache’s owning scope closes.

See

• makeWith for computing time-to-live from each lookup result and key

Signature

declare const make: <Key, A, E = never, R = never, ServiceMode extends "lookup" | "construction" = never>(options: { readonly lookup: (key: Key) => Effect.Effect<A, E, R | Scope.Scope>; readonly capacity: number; readonly timeToLive?: Duration.Input | undefined; readonly requireServicesAt?: ServiceMode | undefined; }) => Effect.Effect<ScopedCache<Key, A, E, "lookup" extends ServiceMode ? Exclude<R, Scope.Scope> : never>, never, ("lookup" extends ServiceMode ? never : R) | Scope.Scope>
