### Voxtral VLLM Plugin (`plugin.ipynb`)

> Plugin implementation for Mistral Voxtral transcription through vLLM
> server

#### Import

``` python
from cjm_transcription_plugin_voxtral_vllm.plugin import (
    VLLMServer,
    VoxtralVLLMPluginConfig,
    VoxtralVLLMPlugin
)
```

#### Functions

``` python
@patch
def supports_streaming(
    self: VoxtralVLLMPlugin # The plugin instance
) -> bool: # True if streaming is supported
    "Check if this plugin supports streaming transcription."
```

``` python
@patch
def execute_stream(
    self: VoxtralVLLMPlugin, # The plugin instance
    audio: Union[AudioData, str, Path], # Audio data or path to audio file
    **kwargs # Additional plugin-specific parameters
) -> Generator[str, None, TranscriptionResult]: # Yields text chunks, returns final result
    "Stream transcription results chunk by chunk."
```
