Struct Classifier 

pub struct Classifier { /* private fields */ }

Thread-safe classifier for bird species detection

Use Classifier::builder() to construct.

Implementations

impl Classifier

pub const fn builder() -> ClassifierBuilder

Create a new classifier builder

pub fn config(&self) -> &ModelConfig

Get the model configuration

pub fn labels(&self) -> &[String]

Get the species labels

pub fn requested_provider(&self) -> ExecutionProviderInfo

Returns the execution provider that was requested for this classifier.

Note: This returns the provider that was requested during build, not necessarily the provider that is actually active. If the requested provider is unavailable, ONNX Runtime will silently fall back to CPU.

This value is only set by the typed with_<provider>() builder methods (e.g., with_cuda(), with_tensorrt()). The generic execution_provider() method does not affect the value returned here.

To verify the actual provider being used, enable ONNX Runtime verbose logging via environment variable: ORT_LOG_LEVEL=Verbose

pub fn predict(&self, segment: &[f32]) -> Result<PredictionResult>

Run inference on a single audio segment

Arguments

• segment - Audio samples (must match config().sample_count)

Returns

• PredictionResult with top predictions, embeddings (if available), and raw scores

Errors

Returns an error if:

• Input segment size doesn’t match expected sample count
• Session lock is poisoned
• ONNX inference fails

pub fn predict_batch( &self, segments: &[&[f32]], ) -> Result<Vec<PredictionResult>>

Run inference on multiple audio segments (more efficient for GPU)

Arguments

• segments - Slice of audio segments (all must match config().sample_count)

Returns

• Vector of PredictionResult, one per input segment

Errors

Returns an error if:

• Any segment size doesn’t match expected sample count
• Session lock is poisoned
• ONNX inference fails

Trait Implementations

impl Clone for Classifier

fn clone(&self) -> Classifier

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Classifier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
