Struct LocalWhisperProvider 

pub struct LocalWhisperProvider { /* private fields */ }

Local whisper.cpp provider.

Implementations

impl LocalWhisperProvider

pub fn new(cache_dir: PathBuf) -> Self

pub fn with_runtime( cache_dir: PathBuf, pool: Arc<SttContextPool>, governor: Arc<ResourceGovernor>, ) -> Self

Construct with an explicit STT pool and governor (JOE-1784 / engine path).

pub fn with_progress(self, show: bool) -> Self

pub fn with_local_only(self, local_only: bool) -> Self

Fail closed if the model is not already on disk (no network).

pub fn with_download_progress(self, cb: DownloadProgressCallback) -> Self

Structured download progress for UI hosts (in addition to optional CLI bar).

pub fn cache_dir(&self) -> &Path

pub fn local_only(&self) -> bool

pub fn is_model_cached(&self, model: &str) -> bool

Whether the ggml file is present and passes basic integrity checks.

pub fn is_model_loaded(&self, model: &str) -> bool

Whether a WhisperContext for this model is already loaded in this provider’s pool.

pub fn pool(&self) -> &Arc<SttContextPool>

pub fn governor(&self) -> &Arc<ResourceGovernor>

pub async fn preload(&self, model: &str) -> Result<PathBuf>

Download (unless local_only) and load the model into this provider’s pool.

pub async fn transcribe_pcm( &self, samples: &[f32], options: &TranscriptionOptions, ) -> Result<TranscriptionResult>

Transcribe a mono PCM buffer (must be WHISPER_SAMPLE_RATE Hz).

Preferred entry point for mic hosts — no temp files, no ffmpeg.

pub async fn transcribe_audio( &self, input: &AudioInput, options: &TranscriptionOptions, ) -> Result<TranscriptionResult>

Transcribe an owned/shared PCM buffer already wrapped as AudioInput.

Trait Implementations

impl TranscriptionProvider for LocalWhisperProvider

fn name(&self) -> &'static str

Human-readable provider name (e.g. "local", "openrouter").

fn backend_kind(&self) -> BackendKind

Backend classification.

fn transcribe<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, input: &'life1 AudioInput, options: &'life2 TranscriptionOptions, ) -> Pin<Box<dyn Future<Output = Result<TranscriptionResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Transcribe audio according to options.

fn timestamps_reliable(&self) -> bool

Whether this provider can emit trustworthy media timestamps.
