## stream

Mistral AI provides the ability to stream responses back to a client in order to allow partial results for certain requests. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message. Otherwise, the server will hold the request open until the timeout or until completion, with the response containing the full result as JSON.

### Example Usage

<!-- UsageSnippet language="typescript" operationID="stream_fim" method="post" path="/v1/fim/completions#stream" -->
```typescript
import { Mistral } from "@mistralai/mistralai";

const mistral = new Mistral({
  apiKey: process.env["MISTRAL_API_KEY"] ?? "",
});

async function run() {
  const result = await mistral.fim.stream({
    model: "codestral-latest",
    prompt: "def",
    suffix: "return a+b",
  });

  for await (const event of result) {
    console.log(event);
  }
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript
import { MistralCore } from "@mistralai/mistralai/core.js";
import { fimStream } from "@mistralai/mistralai/funcs/fimStream.js";

// Use `MistralCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const mistral = new MistralCore({

});

async function run() {
  const res = await fimStream(mistral, {
    model: "codestral-latest",
    prompt: "def",
    suffix: "return a+b",
  });
  if (res.ok) {
    const { value: result } = res;
    for await (const event of result) {
    console.log(event);
  }
  } else {
