Struct objc2::runtime::Sel

#[repr(transparent)]
pub struct Sel { /* fields omitted */ }

A type that represents a method selector.

Implementations

impl Sel

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

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) -> Self

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

Safety

The pointer must a valid, registered selector.

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.
