# Rust SDK

import { Callout } from 'nextra/components'
import { CratesPaused } from '../../components/crates-paused'

All modules share a common `MixnetClient` that manages gateway connections, Sphinx packet encryption, routing, and cover traffic.

<Callout type="info">
Full API reference: [**docs.rs/nym-sdk**](https://docs.rs/nym-sdk/latest/nym_sdk/)
</Callout>

<CratesPaused />

For an overview of what the SDK can do, see the **[Tour](./rust/tour)**. For setup instructions, see [Installation](./rust/importing).

## Modules

- **[Stream](./rust/stream)**: multiplexed `AsyncRead + AsyncWrite` byte streams over the Mixnet. **If you're used to TCP sockets, start here.**

- **[Mixnet](./rust/mixnet)**: raw message payloads, independently routed, no connections or ordering. Use this when you want full control over the communication model.

- **[Client Pool](./rust/client-pool)**: keeps ready-to-use `MixnetClient` instances warm for bursty workloads.

- **[TcpProxy](./rust/tcpproxy)** *(deprecated)*: TCP socket proxying with session management and message ordering. Use Stream for new projects.

- **[FFI](./rust/ffi)**: Go and C/C++ bindings.
