Class Method Details

.register_backend! ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Register the current RBS parsing entrypoints with TreeHaver.

This registers:

  1. the RBS gem backend
  2. the tree-sitter-rbs grammar when the sibling TreeHaver runtime can load it
