Trait gdk_pixbuf::subclass::prelude::InstanceStruct

pub unsafe trait InstanceStruct: Sized + 'static {
    type Type: ObjectSubclass;

    // Provided method
    fn instance_init(&mut self) { ... }
}

Trait implemented by structs that implement a GObject C instance struct.

The struct must be #[repr(C)] and have the parent type’s instance struct as the first field.

See basic::InstanceStruct for a basic implementation of this that can be used most of the time and should only not be used if additional fields are required in the instance struct.

Required Associated Types

type Type: ObjectSubclass

Corresponding object subclass type for this instance struct.

Provided Methods

fn instance_init(&mut self)

Instance specific initialization.

This is automatically called during instance initialization and must call instance_init() of the parent class.

Object Safety

This trait is not object safe.
