Struct objc::runtime::Object

#[repr(C)]
pub struct Object { /* private fields */ }

A type that represents an instance of a class.

Implementations

impl Object

pub fn class(&self) -> &Class

Returns the class of self.

pub unsafe fn get_ivar<T>(&self, name: &str) -> &Twhere T: Encode,

Returns a reference to the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

pub unsafe fn get_mut_ivar<T>(&mut self, name: &str) -> &mut Twhere T: Encode,

Returns a mutable reference to the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

pub unsafe fn set_ivar<T>(&mut self, name: &str, value: T)where T: Encode,

Sets the value of the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

Trait Implementations

impl Debug for Object

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Encode for &'a Object

fn encode() -> Encoding

Returns the Objective-C type encoding for Self.

impl<'a> Encode for &'a mut Object

fn encode() -> Encoding

Returns the Objective-C type encoding for Self.

impl Message for Object

unsafe fn send_message<A, R>( &self, sel: Sel, args: A ) -> Result<R, MessageError>where Self: Sized, A: MessageArguments, R: Any,

Sends a message to self with the given selector and arguments.

fn verify_message<A, R>(&self, sel: Sel) -> Result<(), MessageError>where Self: Sized, A: EncodeArguments, R: Encode,

Verifies that the argument and return types match the encoding of the method for the given selector.
