[−][src]Crate tuple_combinator
A helper trait to improve the ergonomics when working with multiple Option
s. After
importing TupleCombinator
, you can treat a tuple of Option
s as one Option
.
Example
use tuple_combinator::TupleCombinator; fn main() { let tuples = (Some(1), Some(2), Some(3)); assert_eq!(tuples.map(|(a,b,c)| a + b + c), Some(6)); assert_eq!(tuples.and_then(|(a,b,c)| Some(a + b - c)), Some(0)); assert_eq!(tuples.transpose(), Some((1,2,3))); assert_eq!((Some(1), None).map(|(a, b): (i32, i32)| 100), None); }
