#[repr(transparent)]pub struct UICubicTimingParameters(pub id);

Implementations

impl UICubicTimingParameters

pub fn alloc() -> Self

Methods from Deref<Target = Object>

pub fn class(&self) -> &Class

Returns the class of self.

pub unsafe fn get_ivar<T>(&self, name: &str) -> &T where
    T: Encode, 

Returns a reference to the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

Trait Implementations

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

Performs copy-assignment from source.

impl Copy for UICubicTimingParameters

impl Deref for UICubicTimingParameters
