Trait Implementations

impl Clone for Functions

fn clone(&self) -> Functions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Deref for Functions

type Target = FunctionsInner

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
