Struct objc::runtime::Sel

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

A type that represents a method selector.

Implementations

impl Sel

pub fn register(name: &str) -> Sel

Registers a method with the Objective-C runtime system, maps the method name to a selector, and returns the selector value.

pub fn name(&self) -> &str

Returns the name of the method specified by self.

pub unsafe fn from_ptr(ptr: *const c_void) -> Sel

Wraps a raw pointer to a selector into a Sel object.

This is almost never what you want; use Sel::register() instead.

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

Returns a pointer to the raw selector.

Trait Implementations

impl Clone for Sel

fn clone(&self) -> Sel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sel

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

Formats the value using the given formatter.

impl Encode for Sel

fn encode() -> Encoding

Returns the Objective-C type encoding for Self.

impl PartialEq<Sel> for Sel

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

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

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

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