Struct FastembedEmbedderOpts 

pub struct FastembedEmbedderOpts {
    pub cache_dir: Option<PathBuf>,
    pub show_download_progress: bool,
    pub execution: ExecutionPreference,
}

Construction options for FastembedEmbedder.

Default resolves cache_dir in priority order:

1. $LUNARIS_FASTEMBED_CACHE_DIR if set (operator-controllable for CI / sandboxes);
2. ~/.cache/lunaris/models/fastembed/ (shares parent with the candle cache);
3. ./lunaris/models/fastembed/ as a last-ditch fallback when dirs::cache_dir returns None (rare — only on platforms without a HOME concept).

show_download_progress defaults to false so server processes don’t spew progress bars into structured logs. Set true for local CLI use.

Fields

cache_dir: Option<PathBuf>

Filesystem path where fastembed stores auto-downloaded ONNX weights. None means “resolve via the env-override → dirs::cache_dir() chain at Default time”; once Default runs this is always Some(...).

show_download_progress: bool

Forwarded to fastembed::InitOptions::with_show_download_progress. Default false to keep server logs clean.

execution: ExecutionPreference

ORT execution-provider preference (Phase 20 Plan 20-01). Default reads $LUNARIS_FASTEMBED_EXECUTION; unknown values resolve to Cpu with a tracing::warn. Set programmatically when callers want to override the environment.
