Struct UniversalNER 

pub struct UniversalNER { /* private fields */ }

UniversalNER backend for LLM-based zero-shot NER.

Automatically loads API keys from .env if present. Returns explicit errors when unavailable - use is_available() to check.

Implementations

impl UniversalNER

pub fn new() -> Result<Self>

Create a new UniversalNER instance.

Opportunistically loads .env file to check for API keys. Check is_available() before use. Returns an explicit error when unavailable.
