Module: Axn::Core::Flow::Handlers::Invoker

Extended by:
Invoker
Included in:
Invoker
Defined in:
lib/axn/core/flow/handlers/invoker.rb

Overview

Shared block evaluation with consistent arity handling and error piping.

allow_flow_control: when true, done!/fail! (EarlyCompletion/Failure) propagate

out of the handler — use for execution-phase blocks (preprocess, defaults, etc.)
where the user legitimately controls action flow. When false (default), they are
piped as errors — use for post-execution contexts (callbacks, messages, matchers)
where the result is already finalized.
