Defined in:

lib/ruby_lsp/type_guessr/type_inferrer.rb

Overview

Custom TypeInferrer that enhances ruby-lsp’s type inference with TypeGuessr’s IR-based heuristic inference. Used by Go to Definition and other features.

Instance Method Summary

• #infer_receiver_type(node_context) ⇒ GuessedType^?

  Override to add TypeGuessr’s heuristic type inference Returns nil when type cannot be determined (no fallback to ruby-lsp’s default).

• #initialize(index, runtime_adapter) ⇒ TypeInferrer constructor

  A new instance of TypeInferrer.

Constructor Details

#initialize(index, runtime_adapter) ⇒ TypeInferrer

Returns a new instance of TypeInferrer.

#infer_receiver_type(node_context) ⇒ GuessedType^?

Override to add TypeGuessr’s heuristic type inference Returns nil when type cannot be determined (no fallback to ruby-lsp’s default)

Parameters:

• node_context (RubyLsp::NodeContext) —

  The context of the node

Returns:

• (GuessedType, nil) —

  The inferred type or nil if unknown
