Struct glib::subclass::types::InitializingObject

source · [−]

pub struct InitializingObject<T: ObjectSubclass>(_);

Expand description

An object that is currently being initialized.

Binding crates should use traits for adding methods to this struct. Only methods explicitly safe to call during instance_init() should be added.

Implementations

impl<T: ObjectSubclass> InitializingObject<T>

pub unsafe fn as_ref(&self) -> &T::Type

Returns a reference to the object.

Safety

The returned object has not been completely initialized at this point. Use of the object should be restricted to methods that are explicitly documented to be safe to call during instance_init().

pub unsafe fn as_ptr(&self) -> *mut T::Type

Returns a pointer to the object.

Safety

The returned object has not been completely initialized at this point. Use of the object should be restricted to methods that are explicitly documented to be safe to call during instance_init().

pub fn set_instance_data<U: Any + Send + Sync + 'static>(
    &mut self,
    type_: Type,
    data: U
)

Sets instance specific implementation data.

Panics

If the instance_data already contains a data for the specified type_.
