Docs.rs didn't build my crate published on crates.io

I published a crate on crates.io successfully, but I can't find it on docs.rs even wait for hours. The badge shows "no builds".

Is there any way I can know why?

I can build doc locally on stable1.39.0. After I switch to nightly 1.41.0, I got some warning messages like below. This issue on github looks very like what i meet, but it should be fixed one year ago.

warning: `[pid]` cannot be resolved, ignoring it...

    = help: to escape `[` and `]` characters, just add '\' before them like `\[` or `\]`

Just saw there was issue with docs.rs which should be fixed already https://twitter.com/rustlang/status/1198691339984093185 . It's not related to your nightly build error though, only seems related to propagation to docs.rs
