LangExtract.Template (LangExtract v0.11.0)

The extraction task definition: a plain-language description of what to extract, plus few-shot examples showing the expected output.

There is no schema DSL and no fine-tuned model — the template is rendered into a few-shot prompt by LangExtract.Prompt.Builder, and the examples are what teach the model the class vocabulary, span granularity, attributes, and output format.

Build templates with LangExtract.template/2, which accepts plain maps for examples (string or atom keys, so JSON-loaded task definitions work verbatim) and validates them against the production aligner, raising on malformed or misaligned input. The struct is public for pattern matching and introspection.
