class Bindgen::Graph::Struct

Overview

A struct in Crystal (lib or not), or a plain struct in C++.

A structure can host both raw non-static variable fields (C-style) and other methods at once.

Defined in:

bindgen/graph/struct.cr

Constant Summary

COPY_BASE_CONSTRUCTOR_TAG = "COPY_BASE_CONSTRUCTOR_TAG"

Used to signal the Generator::Cpp to generate a constructor copying an instance of the base class, which isn't inherited by the above.

INHERIT_CONSTRUCTORS_TAG = "INHERIT_CONSTRUCTORS_TAG"

Used to signal the Generator::Cpp to generate a using BASE::BASE;.

Instance Method Detail

def base_class : String | Nil #

Name of the base-class, if any. This is mainly useful for C++ to generate the jump-table.


[View source]
def base_class=(base_class : String | Nil) #

Name of the base-class, if any. This is mainly useful for C++ to generate the jump-table.

def bit_fields : Array(Bindgen::Graph::Struct::BitField) #

Bit-fields of a lib struct, which get getter and setter methods.


[View source]
def field_defaults : Hash(String, String) #

Default member initializers of #fields, by name, as C++ expressions: nullptr. Only Generator::Cpp writes them.


[View source]
def fields : Hash(String, Call::Result) #

Non-static fields in this structure.


[View source]
def packed? : Bool #

Are the fields packed without alignment, as in a @[Packed] struct?
