Struct tylisp::ops::If[−][src]

pub struct If;
Expand description

TyLisp primitive conditional operator

Takes three parameters, Cond, T, and F.

  • If Cond is typenum::True, evaluates to T
  • If Cond is typenum::False, evaluates to F

The non-selected branch does not need to be valid. This statement is invalid if Cond evaluates to anything other than True or False.
