Instance Method Details

#define_jit_method(name, function) ⇒ Object

Use a Function to define an instance method on a module. The function should have one of two signatures:

• The first parameter to the function should be an OBJECT that represents the self parameter and the rest of the parameters, or

• The function’s signature should be Type::RUBY_VARARG_SIGNATURE.
