Convert a dsprrr module into a vitals solver — as_vitals

Creates a function compatible with vitals Tasks that executes a DSPrrr module against batches of inputs. The solver forwards arguments to run_dataset() and returns vitals-friendly objects containing results, chat logs, and metadata.

Usage

as_vitals_solver(
  module,
  .llm = NULL,
  .parallel = FALSE,
  .return_format = "structured",
  .input_column = NULL,
  ...
)

Arguments

module: A DSPrrr module (e.g., created via module()).
.llm: Optional ellmer chat object. When NULL, each invocation will create a fresh default client.
.parallel: Logical; forwarded to run_dataset(). Defaults to FALSE to avoid sharing LLM state across workers.
.return_format: One of "structured" (default) or "simple".
.input_column: Column name to use for the module's input. Defaults to the first input name from the module's signature. Used to map vitals' "input" column to the module's expected input column.
...: Additional arguments forwarded to run_dataset().

Value

A function accepting a data frame of inputs and returning a list with components result, solver_chat, and metadata.
