Module: RBS

Defined in:

lib/rigor/cache/rbs_environment_marshal_patch.rb

Overview

Adds _dump / _load to Location so an RBS::Environment (and its transitive AST nodes, all of which carry Locations) round-trips through Marshal. The rbs gem's C-extension RBS::Location ships without the Marshal hooks; until rbs grows them upstream this patch is the minimal monkey-patch the v0.0.9 RBS::Environment cache relies on.

Patch policy (purely additive):

• _dump returns an empty string. The cached env loses per-node source-position info, but Rigor does not consult RBS::Location from any analysis code path (every diagnostic uses Prism's own location), so the loss is inert in practice.
• _load reconstructs a sentinel Location backed by an empty <cached> Buffer. Code paths that DID consult Location after a cache hit see a benign zero-range value rather than crashing.

Idempotent: the guard checks method_defined?(:_dump) so requiring this file twice (or against an upstream rbs that adds Marshal hooks itself) is a no-op.
