Trait Implementations

impl Clone for NotNull

fn clone(&self) -> NotNull

Returns a duplicate of the value.

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

fn eq(&self, other: &NotNull) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
