Struct cglue::trait_group::CGlueObjContainer

#[repr(C)]
pub struct CGlueObjContainer<T, C, R> { /* private fields */ }

Simple CGlue trait object container.

This is the simplest form of container, represented by an instance, clone context, and temporary return context.

instance value usually is either a reference, or a mutable reference, or a CBox, which contains static reference to the instance, and a dedicated drop function for freeing resources.

context is either PhantomData representing nothing, or typically a CArc that can be cloned at will, reference counting some resource, like a Library for automatic unloading.

ret_tmp is usually PhantomData representing nothing, unless the trait has functions that return references to associated types, in which case space is reserved for wrapping structures.
