Rename AsyncCoroutineKind to CoroutineSource pulled out of rust-lang/rust#116447 Also refactors the printing infra of `CoroutineSource` to be ready for easily extending it with a `Gen` variant for `gen` blocks
Implement `gen` blocks in the 2024 edition Coroutines tracking issue rust-lang#43122 `gen` block tracking issue rust-lang#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
Opened #118219 to fix this. |
Add support for `gen fn` This builds on rust-lang#116447 to add support for `gen fn` functions. For the most part we follow the same approach as desugaring `async fn`, but replacing `Future` with `Iterator` and `async {}` with `gen {}` for the body. The version implemented here uses the return type of a `gen fn` as the yield type. For example: ```rust gen fn count_to_three() -> i32 { yield 1; yield 2; yield 3; } ``` In the future, I think we should experiment with a syntax like `gen fn count_to_three() yield i32 { ... }`, but that can go in another PR. cc `@oli-obk` `@compiler-errors`
