Trait Implementations

impl AsRef<CGContextRef> for CGContext

fn as_ref(&self) -> &CGContextRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<CGContextRef> for CGContext

fn borrow(&self) -> &CGContextRef

Immutably borrows from an owned value.

impl ToOwned for CGContextRef

type Owned = CGContext

The resulting type after obtaining ownership.

fn to_owned(&self) -> CGContext

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.
