#[repr(C)]
pub struct Class(_);

A type that represents an Objective-C class.

Implementations

impl Class

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

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

pub fn classes() -> Malloc<[&'static Self]>

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 the class.

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

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

pub fn metaclass(&self) -> &Self

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) -> Malloc<[&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) -> Malloc<[&Protocol]>

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

pub fn instance_variables(&self) -> Malloc<[&Ivar]>

Describes the instance variables declared by self.

Trait Implementations

impl Debug for Class

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

Formats the value using the given formatter.

impl Hash for Class

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,

impl<'a> MessageReceiver for &'a Class

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

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

unsafe fn send_super_message<A, R>(
    self,
    superclass: &Class,
    sel: Sel,
    args: A
) -> Result<R, MessageError> where
    A: MessageArguments,
    R: Encode,
