Trait DispatchableHandle 

pub trait DispatchableHandle: Handle<Repr = usize> {
    // Provided method
    unsafe fn dispatch_key(self) -> usize { ... }
}

A Handle with a representation of usize (a pointer to an opaque type).

Provided Methods

unsafe fn dispatch_key(self) -> usize

Gets the dispatch key for this dispatchable handle.

As described in the driver interface to the Vulkan loader, all dispatchable handles created by Vulkan drivers can be cast to void** (a.k.a., *mut *mut c_void). The Vulkan loader will always replace the first entry in this array of pointers with a pointer to the dispatch table (created and owned by the loader) for the dispatchable handle. This guarantee can be used to extract a key from a dispatchable handle that is stable and unique to an Instance or Device or the Instance or Device another type of dispatchable device is associated with (e.g., a CommandBuffer is associated with the Device it was created for).

Safety

This handle must be a valid Vulkan dispatchable handle.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
