Struct Protocol 

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

Objective-C protocol.

A protocol defines a set of methods that a class can implement.

Implementations

impl Protocol

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

Look up a protocol by name.

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

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

Check if this protocol declares an instance method with the given selector.

Checks both required and optional methods.

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

Check if this protocol declares a class method with the given selector.

Checks both required and optional methods.

pub fn is_null(&self) -> bool

Returns true if this protocol pointer is null.

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

Returns the raw pointer value.

Trait Implementations

impl Clone for Protocol

fn clone(&self) -> Protocol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Protocol

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

Formats the value using the given formatter.

impl Hash for Protocol

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 Protocol

fn eq(&self, other: &Protocol) -> 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.
