# Client

This page lists the Rust SDK names for the [Client](https://docs.superdurable.io/zh-Hans/concepts/client.md).
The doc comment of each API gives its parameters, defaults, and errors. Read
them in the [Rust SDK API reference](https://docs.superdurable.io/zh-Hans/reference/rust.md#api-reference).
