Types

type Adapter

type Adapter struct {
	// contains filtered or unexported fields
}

Adapter is an unbounded L1 cache backed by sync.Map.

This is the default L1 adapter used when no custom adapter is configured. It offers excellent performance under read-heavy workloads but provides no eviction, no size limits, and no cost awareness.

For production services with memory constraints, consider a bounded adapter backed by Ristretto, Theine, or Otter.

New returns a new sync.Map-backed L1 adapter.
