Struct objc::runtime::Class

#[repr(C)]
pub struct Class { /* fields omitted */ }

A type that represents an Objective-C class.

Methods

impl Class

pub fn get(name: &str) -> Option<&'static Class>

Returns the class definition of a specified class, or None if the class is not registered with the Objective-C runtime.

pub fn classes() -> MallocBuffer<&'static Class>

Obtains the list of registered class definitions.

pub fn classes_count() -> usize

Returns the total number of registered classes.

pub fn name(&self) -> &str

Returns the name of self.

pub fn superclass(&self) -> Option<&Class>

Returns the superclass of self, or None if self is a root class.

pub fn metaclass(&self) -> &Class

Returns the metaclass of self.

pub fn instance_size(&self) -> usize

Returns the size of instances of self.

pub fn instance_method(&self, sel: Sel) -> Option<&Method>

Returns a specified instance method for self, or None if self and its superclasses do not contain an instance method with the specified selector.

pub fn instance_variable(&self, name: &str) -> Option<&Ivar>

Returns the ivar for a specified instance variable of self, or None if self has no ivar with the given name.

pub fn instance_methods(&self) -> MallocBuffer<&Method>

Describes the instance methods implemented by self.

pub fn conforms_to(&self, proto: &Protocol) -> bool

Checks whether this class conforms to the specified protocol.

pub fn adopted_protocols(&self) -> MallocBuffer<&Protocol>

Get a list of the protocols to which this class conforms.

pub fn instance_variables(&self) -> MallocBuffer<&Ivar>

Describes the instance variables declared by self.

Trait Implementations

impl<'a> Encode for &'a Class

fn encode() -> Encoding

Returns the Objective-C type encoding for Self.

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

fn encode() -> Encoding

Returns the Objective-C type encoding for Self.

impl Message for Class

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.

impl PartialEq<Class> for Class

fn eq(&self, other: &Class) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Eq for Class

impl Debug for Class

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