Struct NerDetector 

pub struct NerDetector { /* private fields */ }

NER detector backed by a pinned local model artifact set. Multiple NerDetector instances with different backends may be stacked in the same Pipeline; span-conflict resolution picks winners across detectors.

Implementations

impl NerDetector

pub fn load(model_dir: &Path) -> Result<Self, NerLoadError>

Full load: verify artifacts, initialize the configured backend. Fails closed on any load error.

pub fn load_with_options( model_dir: &Path, options: NerOptions, ) -> Result<Self, NerLoadError>

pub fn locale(&self) -> Option<&str>

pub fn backend_kind(&self) -> NerBackendKind

pub fn recognizer_version_id(&self) -> &str

pub fn merge_bio_spans( labels: &LabelMap, subword_spans: &[(usize, usize)], subword_labels: &[&str], source: &str, ) -> Vec<Detection>

Label/offset reconstruction helper. Public for testing the BIO merge. subword_spans are byte ranges against the tokenizer input string, subword_labels are CoNLL-style labels per subword (e.g. O, B-PER, I-PER). Returns merged detections, dropping labels absent from the label map and subword spans overlapping special tokens (empty ranges).

pub fn merge_bio_span_results( labels: &LabelMap, subword_spans: &[(usize, usize)], subword_labels: &[&str], subword_scores: &[f32], source: &str, ) -> Vec<NerSpanResult>

impl NerDetector

pub fn verify_artifacts( model_dir: &Path, ) -> Result<VerifiedArtifacts, NerLoadError>

Verify SHA256SUMS, parse labels.json and config.json. No backend initialization. Used both by load and by unit tests.

Trait Implementations

impl Debug for NerDetector

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

Formats the value using the given formatter.

impl Detector for NerDetector

fn detect(&self, input: &str) -> Vec<Detection>

Detect PII spans in the supplied input string.

fn try_detect( &self, input: &str, ) -> Result<Vec<Detection>, RecognizerRuntimeError>

Fallible detection entrypoint for detectors backed by runtime systems.
