Turns IntoStream into a regular struct because pin_project_lite does not and will support tuple structs. https://github.com/taiki-e/pin-project-lite/blob/416be96f7777862c68b567c92a91887f69a8c2b3/src/lib.rs#L401-L408
This enables migration to pin_project_lite, which does not and will not support tuple structs https://github.com/taiki-e/pin-project-lite/blob/416be96f7777862c68b567c92a91887f69a8c2b3/src/lib.rs#L401-L408
Note: the doc comment on AsyncResponseFuture::service was also reduced to a regular comment. This is a known limitation of pin_project_lite that the they have labeled as "help wanted". taiki-e/pin-project-lite#3 (comment)
pin_project_lite has the current limitation of nto supporting doc comments taiki-e/pin-project-lite#3 (comment) pin_project_lite does not and will not support tuple variants https://github.com/taiki-e/pin-project-lite/blob/416be96f7777862c68b567c92a91887f69a8c2b3/src/lib.rs#L401-L408
peak_wma and pending_requests will now properly compile without the "discover" feature enabled.

Running the tests on both stable and nightly pass locally for me. On nightly, I do receive multiple warnings about a lint renaming. I'd appreciate any advice on how to diagnose further. On Stable $ rustc --version
rustc 1.53.0 (53cb7b09b 2021-06-17)
$ cargo test --all --all-features
(passes)On Nightly $ rustc +nightly --version
rustc 1.56.0-nightly (08095fc1f 2021-07-26)
$ cargo +nightly test --all --all-features

= note: `#[warn(renamed_and_removed_lints)]` on by default |

@Michael-J-Ward are you able to rename it? or is it not available on stable yet? |
broken_intra_doc_links has been renamed to rustdoc::broken_intra_doc_links

I should have been clearer- the lint warning was not the reason for the failure. This test below is failing in CI but I can't trigger the failure locally. Running tests/spawn_ready/main.rs (target/debug/deps/spawn_ready-102042b79d40a5b4)

@taiki-e are there any differences in drop behavior between pin project and pin project lite? |
pin_project_lite does support PinnedDrop https://github.com/taiki-e/pin-project-lite/pull/25/files However, it does not support generic trait bounds on the PinnedDrop impl. To workaround this, I removed the T::Error bound from the Worker struct definition, and moved `close_semaphore` to a a new impl without that trait bound.
I don't think so. |

After updating cargo and disabling / clearing out sccache, I am able to reproduce the However, |
This test was also failing on master.

Clears out the easy parts of #594.
Remaining:
util::Either- it is public and the migration requires a breaking change (as described here)buffer::worker- would love to take a shot at the refactor with a little more guidance.
