Trait DynamicLabels 

pub trait DynamicLabels: Model {
    // Required method
    fn extract_with_labels(
        &self,
        text: &str,
        labels: &[&str],
        language: Option<&str>,
    ) -> Result<Vec<Entity>>;
}

Trait for models that support dynamic/zero-shot entity type specification.

Models implementing this trait can extract entities of arbitrary types specified at inference time (e.g., GLiNER, UniversalNER), rather than being limited to a fixed set of pre-trained types.

Required Methods

fn extract_with_labels( &self, text: &str, labels: &[&str], language: Option<&str>, ) -> Result<Vec<Entity>>

Extract entities with custom type labels.

Arguments

• text - Input text to extract from
• labels - Custom entity type labels to extract (e.g., [“PERSON”, “ORGANIZATION”])
• language - Optional language hint (e.g., “en”, “es”)

Returns

Entities of the specified types found in the text.
