rustkit's Introduction

RustKit

Fast and ergonomic Rust bindings for ObjC APIs

RustKit is currently under development. Please try it if you want to contribute or provide feedback on the generated bindings.

Prerequisites

Clang 8.0 (currently trunk) with a patch is currently required. Build clang and set the LIBCLANG_PATH environmental variable to the directory that libclang.dylib is in, which should be in the lib directory of your clang/llvm build directory.

Example

extern crate rustkit;

use rustkit::NSObject;

fn main() {
    let obj = NSObject::new();
    
    let desc = NSObject::description();
    let desc = desc.unwrap();
    let desclen = desc.length();
    let ruststr: String =
        (0..desclen).map(|i|
                         std::char::from_u32(desc.characterAtIndex_(i) as u32).
                         unwrap()).collect();
    println!("NSObject::description(): {}", ruststr);
}

Build broken due to duplicate 'new' method generation

Hi, I tried building against the Xcode 11.3 SDK. The build errors out with numerous errors of this kind:

error[E0201]: duplicate definitions with name `new`:
     --> src/RustKit/target/debug/build/rustkit-74ad679636d80c03/out/Foundation.rs:75054:5
      |
75042 | /     pub fn new() -> Arc<Self> {
75043 | |         unsafe {
75044 | |             let send: unsafe extern "C" fn(*mut Object, SelectorRef) -> *mut Self =
75045 | |                 mem::transmute(objc_msgSend as *const u8);
...     |
75052 | |         }
75053 | |     }
      | |_____- previous definition of `new` here
75054 | /     pub fn new() -> Arc<Self> {
75055 | |         unsafe {
75056 | |             let send: unsafe extern "C" fn(*mut Object, SelectorRef) -> *mut Self =
75057 | |                 mem::transmute(objc_msgSend as *const u8);
...     |
75064 | |         }
75065 | |     }
      | |_____^ duplicate definition

I think it is trying to generate the same method for the init and new Objective-C methods, both of which are marked deprecated, by the way.

Appreciate any assistance. Thanks!

Lots of snake_case warnings

e.g.

warning: structure field `decodeTimeStamp` should have a snake case name such as `decode_time_stamp`
     --> /Users/jrmuizel/src/RustKit/target/debug/build/rustkit-aac91a27cd0abb1d/out/CoreMedia.rs:13876:5

feature RK_AppKit, produces aliased parameters

Compiling with feature RK_AppKit

Produces

pub fn renameFontCollectionWithName_visibility_toName_error_(
         name: &NSString,
         visibility: NSFontCollectionVisibility,
         name: &NSString,
         error: Option<&mut &Option<Arc<NSError>>>,
     ) -> bool {

Resulting in
error[E0415]: identifier `name` is bound more than once in this parameter list
