The right-hand side of any value expression. Ducttape originally had another rhs type: Sequential branchpoint expressions, written (Branchpoint: 0..10..1).

Trait Implementations

impl<'a> Debug for Rhs<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq for Rhs<'a>

fn eq(&self, other: &Rhs<'a>) -> 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.
