[−][src]Trait trait_eval::If
Conditional execution!
The syntax is kind of clunky, but write <(Then, Else) as If<Cond>::Result. The condition can
be any boolean expression built using True, False,
AndAlso, OrElse and Not.
Talk about feature complete.
assert_eq!(<(Three, Four) as If<True>>::Result::eval(), 3); assert_eq!(<(Three, Four) as If<False>>::Result::eval(), 4);
