Trait CIPlugInRegistration 

pub unsafe trait CIPlugInRegistration {
    // Provided method
    unsafe fn load(&self, host: *mut c_void) -> bool
       where Self: Sized + Message { ... }
}

Available on crate feature CIPlugInInterface only.

This protocol defines the calls made by the host to the CIPlugIn when initializing it

The principal class of a CIPlugIn must support the CIPlugInRegistration protocol

See also Apple’s documentation

Provided Methods

unsafe fn load(&self, host: *mut c_void) -> bool

where Self: Sized + Message,

the plugin gets a chance to do custom initialization (like registration check ) here

Load gets called once by the host when the first filter from the plug-in gets instantiated. Return of true means that the plugIn successfully initialized

Parameter host: for future use only

Safety

host must be a valid pointer.
