Trait glib::translate::FromGlibPtrNone
source · pub trait FromGlibPtrNone<P: Ptr>: Sized {
// Required method
unsafe fn from_glib_none(ptr: P) -> Self;
}Expand description
Translate from a pointer type which is annotated with transfer none.
The resulting value is referenced at least once, by the bindings.
This is suitable for floating references, which become strong references.
It is also suitable for acquiring non-gobject values, like gchar*.
Safety
The implementation of this trait should acquire a reference to the value
in a way appropriate to the type,
e.g. by increasing the reference count or copying.
Values obtained using this trait must be properly released on drop()
by the implementing type.
For more information, refer to module level documentation.
