Module client 

The top-level Client and its builder.

A Client is the user-facing entry point: it owns the transport engine and hands out per-tag sub-clients (orgs, devices, entities, …) on demand.

Structs

Client

High-level SDK client. Cheap to clone — all heavy state sits behind an Arc.

ClientBuilder

Fluent builder for Client. Use Client::builder to construct one.

ClientConfig

User-visible client configuration snapshot (read-only after ClientBuilder::build).
