[bors]

🕐 Waiting for PR status (Github check) to be set, probably by CI. Bors will automatically try to run when all required PR statuses are set.

[yangby-cryptape]

Checks can't completed and bors doesn't work.
Let administrator do merge or force-push to rerun Checks after git commit --amend.

[bors]

GitHub status checks took too long to complete, so bors is giving up. You can adjust bors configuration to have it wait longer if you like.
