What is ArgDigest?

ArgDigest is a lightweight, extensible library to audit, normalize, and validate function arguments in scientific Python libraries.

It provides two complementary mechanisms:

• Argument-centric digestion: per-argument digesters that validate or coerce values.

• Pipeline-based validation: reusable rules grouped by kind and executed in order.

ArgDigest is domain-agnostic by design. Each library provides its own digestion logic while ArgDigest supplies the execution engine, error model, and optional discovery utilities.
