pub macro iter($($t:tt)*) {
...
}
🔬This is a nightly-only experimental API. (
iter_macro
)Expand description
Creates a new closure that returns an iterator where each iteration steps the given
generator to the next yield
statement.
Similar to iter::from_fn
, but allows arbitrary control flow.
§Examples
#![feature(iter_macro, coroutines)]
let it = std::iter::iter!{|| {
yield 1;
yield 2;
yield 3;
} }();
let v: Vec<_> = it.collect();
assert_eq!(v, [1, 2, 3]);
