bors 2cad938a81 Auto merge of #116447 - oli-obk:gen_fn, r=compiler-errors ... Implement `gen` blocks in the 2024 edition Coroutines tracking issue https://github.com/rust-lang/rust/issues/43122 `gen` block tracking issue https://github.com/rust-lang/rust/issues/117078 This PR implements `gen` blocks that implement `Iterator`. Most of the logic with `async` blocks is shared, and thus I renamed various types that were referring to `async` specifically. An example usage of `gen` blocks is ```rust fn foo() -> impl Iterator<Item = i32> { gen { yield 42; for i in 5..18 { if i.is_even() { continue } yield i * 2; } } } ``` The limitations (to be resolved) of the implementation are listed in the tracking issue		2023-10-29 00:03:52 +00:00
