remove async_std framework in favor of tokio
async-std
has only been used in the prototype of transceive
command. However, when using external crates such as domain
, the async runtime of choice seems to be tokio
. It seems redundant to have two async runtimes and while I liked the simpler approach of async-std
, the tokio
runtime is way more widespread and respdiff-rs
would end up pulling it as a transitive dependency anyway, so let's use tokio
instead.
