module Rubellite::TypedData(T)

Overview

Coordinates zero-copy object wrapping between Crystal classes/structs and CRuby RTypedData. Guarantees dual-GC safety by pinning Crystal objects in Boehm GC on creation, and unpinning them via the CRuby dfree callback when the Ruby object is swept.

Defined in:

rubellite/typed_data.cr

Class Method Summary

• .def_method(method_name : String, &block : T, Array(Value) -> Value) : Nil

  Defines an instance method on the CRuby class that receives the unwrapped Crystal self

• .info : TypeDescriptor

  Returns the registered TypeDescriptor for T, initializing it on first access

• .typed_data?(val : Value) : Bool

  Checks if a CRuby Value wraps an instance of T

• .unwrap(val : Value) : T

  Unwraps a CRuby RTypedData Value back into the underlying Crystal instance.

• .unwrap?(val : Value) : T | Nil

  Safely unwraps a CRuby RTypedData Value, returning nil if the type does not match

• .wrap(obj : T) : Value

  Wraps a Crystal object into a CRuby RTypedData Value with zero memory copy

• .wrap_name=(name : String) : Nil

  Sets a custom Ruby class name for this type
