The intent is also clearer if only a single -operation is being performed. - -### Example -``` -let _ = (0..3).filter_map(|x| if x > 2 { Some(x) } else { None }); - -// As there is no transformation of the argument this could be written as: -let _ = (0..3).filter(|&x| x > 2); -``` - -``` -let _ = (0..4).filter_map(|x| Some(x + 1)); - -// As there is no conditional check on the argument this could be written as: -let _ = (0..4).map(|x| x + 1); -```
