Hi, I'd gladly accept a PR to update those !

Thanks it looks good. However I think the `if` are getting a bit too nested, could you refactor it with a `cond` and `and` conditions ?

Thanks for pointing out this tricky issue, I released `0.4.2` with the locking fix, let me know how it goes.

It's a possibility indeed, but it's a lot of refactoring. If everything is fine, I'd accept such a PR though.

Hi, thank you for your investigations. I released version `v0.3.4` with `PING` and `ECHO` support. However as you said I am not sure it is necessary to implement all the...

In [this](https://github.com/tantivy-search/tantivy/issues/563#issuecomment-805177242) comment @maufl suggested an alternative specialization based implementation to address the `A::State` type issue. I can update this PR with it if needed.

Could this be solved by leveraging `StreamWithState` from `fst` crate which is now available (details in [this commit](https://github.com/BurntSushi/fst/commit/fc757c65467d8033019de37c990b302bfbf43276)) ?
