The existing implementation has accumulated a lot of crust from initial
async support and use of hyper. Now that is using reqwest we can do many
things simpler.

Removed things that were needed for hyper but are handled already by
reqwest:

  • setting the proxy
  • setting the auth header
  • setting the content type header
  • setting content length header

Other changes:

  • Move from struct with Future impl to BoxFuture. We were already using
    BoxFuture internally anyawy.
  • Log request and response as debug strings. This makes sure no control
    characters like newlines end up in the output.
  • Use from_utf8_lossy for the response log so that we can still
    partially log non utf8 responses.
  • Fix not handling batch responses according to the jsonrpc
    specification which does not guarantee the ordering of the list.
  • Add more context to error logs.

Looks good, thanks a lot! The WASM build requires a tiny fix.

- Allow giving a custom client to the transport. This is useful for
example to set a timeout.

Looks like you can't set a user agent on wasm, which makes sense as the browser probably uses its own. Let's see if this fixes the build.

Awesome, one last bit is WASM-build warning, and we're good to go :)
