Trait Implementations

impl AsRef<CGContextRef> for CGContext

pub fn as_ref(&self) -> &CGContextRef

Performs the conversion.

impl Borrow<CGContextRef> for CGContext

pub fn borrow(&self) -> &CGContextRef

Immutably borrows from an owned value.

impl ToOwned for CGContextRef

type Owned = CGContext

The resulting type after obtaining ownership.

pub fn to_owned(&self) -> CGContext

Creates owned data from borrowed data, usually by cloning.

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

🔬 This is a nightly-only experimental API. (toowned_clone_into)

recently added

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