cargo doc fails due to too deep recursion

[sticnarf]

cargo doc produces errors like this:

error[E0275]: overflow evaluating the requirement `alloc::raw_vec::RawVec<(syn::Lifetime, syn::token::Add)>: std::marker::Unpin`

Related to rust-lang/rust#62059. It is solved by rust-lang/rust#62450. So simply upgrading the compiler can solve the problem

Is this why the doc page is empty in both Firefox and Chromium? https://docs.rs/tikv-client/0.0.0/tikv_client/
it's linked in https://github.com/tikv/client-rust#access-the-documentation

it actually works fine locally, ie.

$ git clone https://github.com/tikv/client-rust.git
$ cd client-rust 
$ cargo doc --package tikv-client --open

EDIT: ok got it, it will work when #32 is closed, thanks

We haven't published this yet (because we currently depend on a git repo), it's coming soon!
