Formats the value using the given formatter.

impl PartialEq for Builtin

fn eq(&self, other: &Builtin) -> 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.
