Struct objc_sys::objc_protocol

source · 
#[repr(C)]
pub struct objc_protocol { /* private fields */ }
Expand description

Opaque type for Objective-C protocols.

Note that, although protocols are objects, sending messages to them is deprecated and may not work in the future.

The naming of this follows GNUStep; this does not exist in Apple’s original, there Protocol is just a type alias of objc_object.
