#[derive(Iterator, DoubleEndedIterator, ExactSizeIterator, FusedIterator, Extend)] for enums.
Add this to your Cargo.toml
:
[dependencies]
iter-enum = "1"
use iter_enum::*;
#[derive(Iterator, DoubleEndedIterator, ExactSizeIterator, FusedIterator, Extend)]
enum Either<A, B> {
A(A),
B(B),
}
fn foo(x: i32) -> impl Iterator<Item = i32> {
if x > 0 {
Either::A(x..=0)
} else {
Either::B(Some(x).into_iter())
}
}
See auto_enums crate for how to automate patterns like this.
