# server-rs

An Axum API example using the Rust components with mock inference.
Requests use DeepSeek V4.1 prompt rendering and OpenCV image preprocessing.

## Usage

Install the [Rust and OpenCV prerequisites](../docs/development.md#native-dependencies), then run
from the repository root:

```sh
cargo run -p server-rs --locked
```

The server listens on `127.0.0.1:7777`. Set `SERVER_ADDR` to change the address.

## API

- `POST /v1/chat/completions`
- `POST /v1/responses`
- `POST /v1/messages`

All three protocols support JSON for `stream=false` and SSE for `stream=true`.

For example, in a second terminal:

```sh
curl http://127.0.0.1:7777/v1/chat/completions \
  -H 'Content-Type: application/json' \
  -d '{"model":"deepseek-flash","messages":[{"role":"user","content":"Hello"}],"stream":false}'
```

The response contains the mock answer `Hello world!`. Set `"stream":true` and
add `-N` to curl to inspect SSE output. No API key or model weights are required.

## Deployment scope

This example has no authentication and uses an image fetcher that does not
filter private network addresses. Keep it on loopback for local use; see the
[deployment considerations](../docs/development.md#example-servers) before
exposing it to other users. The Python example uses the same default port.
