Overview

A live, read-only, dict-like view of a config’s resolved values.

Returned by ConfigClient#subscribe. Always reflects the latest server-pushed state — every read sees current values.

Supports [], key?, keys, values, each_pair, to_h, size, and method-style attribute access for keys that don’t collide with built-in method names. Use subscript (+proxy+) for keys that do collide.

For typed access via a Struct schema, use ConfigClient#bind — bound objects stay live on the same cache, with no proxy indirection.
