Struct ClassBuilder 

pub struct ClassBuilder { /* private fields */ }

A class being built. Add methods, then register.

Implementations

impl ClassBuilder

pub unsafe fn new(superclass: &CStr, name: &CStr) -> Option<Self>

Begin a new class, or return None if the name is already taken.

Safety

superclass must name a registered class.

pub unsafe fn method( self, selector: &CStr, imp: *const c_void, types: &CStr, ) -> Self

Add a method.

types is an Objective-C type encoding: return type, then @: for the implicit receiver and selector, then one code per argument. B@:@@ is “returns BOOL, takes two objects”.

Safety

imp’s signature must match types, receiver and selector included.

pub unsafe fn conforms(self, protocol: &CStr) -> Self

Declare conformance to a protocol.

Safety

The class must actually implement the protocol’s required methods.

pub fn register(self) -> *mut c_void

Register the class with the runtime and return it.
