SnakeBridge.Dynamic (SnakeBridge v0.7.4)

View Source

Dynamic dispatch for calling methods on Python objects without generated code.

Use this module when:

  • Python returns an object of a class you did not generate bindings for
  • You need to call methods dynamically at runtime
  • You want a no-codegen escape hatch for refs
