Helper struct for nil constant

Trait Implementations

impl<T> PartialEq<Nil> for Nullable<T>

fn eq(&self, _: &Nil) -> 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.
