Defined in:
lib/braintrust/scorer.rb

Overview

Block-based scorer. Stores a Proc and delegates #call to it. Includes Scorer so it satisfies Scorer === checks (e.g. in Context::Factory). Exposes #call_parameters so KeywordFilter can introspect the block’s declared kwargs rather than Block#call’s **kwargs signature.
