Constructor Detail

def self.new(this : Block, names : Array(Word), types : Array(Word), comment : Nil | String) #

Initializes a struct layout form. Names array names must be created uniquely for this form, because it will be used as this struct layout form's identity during deep recursion checks etc.

this block is going to be used for lookup of user-defined struct layouts (e.g. &foobar).


def self.new(layout : Novika::FFI::StructLayout, comment : Nil | String) #

Initializes a struct layout form from the given layout. The layout must contain at least one field.

def object_id(*args, **options) #
