Module: SimpleCov::Formatter::AIFormatter::ASTResolver::NodeChildren

Extended by:
T::Sig
Defined in:
lib/simplecov-ai/ast_resolver/node_children.rb

Overview

Typed access to the children of Parser AST nodes. Parser types every child as untyped while each node type the resolver reads has one known shape (:def holds its name Symbol first, :casgn its scope node, name Symbol and value node), so the casts live here and every call site names the child it reads and nothing else.
