This pull request adds two default features
runtime-tokio
andconnector-hyper
, which control if the default runtime / connector implementation is present.This change makes it possible to use this crate in environments where Tokio and/or hyper cannot be used, and the end user wants to provide their own Connector implementation (e.g. Cloudflare Worker (worker-rs, Fetch), Phala Network (sidevm, see #266)).
Notably,
Api::send_timeout
currently depends on Tokio, so we have to disable that ifruntime-tokio
is not selected. In those cases, we are forced to useApi::send
without timeouts inUpdatesStream
. This may be suboptimal, but should yield correct behavior nevertheless.
