Struct Class 

pub struct Class(/* private fields */);

Objective-C class.

A class is a blueprint for creating objects. Classes are looked up by name from the runtime.

Implementations

impl Class

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

Look up a class by name.

Returns None if the class is not registered with the runtime.

pub unsafe fn get_cstr(name: *const c_char) -> Option<Self>

Look up a class from a null-terminated C string.

Safety

The pointer must be a valid null-terminated C string.

pub fn as_ptr(&self) -> *const c_void

Returns the raw pointer value.

pub fn is_null(&self) -> bool

Returns true if this class pointer is null.

pub fn instances_respond_to(&self, sel: Sel) -> bool

Check if instances of this class respond to the given selector.

Returns true if the class has an instance method for the selector.

pub fn responds_to(&self, sel: Sel) -> bool

Check if this class responds to the given selector (class method).

Returns true if the class has a class method for the selector.

pub unsafe fn name(&self) -> &'static str

Get the name of this class.

Safety

The class pointer must be valid.

Trait Implementations

impl Clone for Class

fn clone(&self) -> Class

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Class

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Class

impl Send for Class

impl StructuralPartialEq for Class
