BareProxy 0.3.0 Writes Its Plugins in Rust, Where a Plugin Adds 15 Microseconds Instead of 42

BareProxy 0.3.0 is out. It doesn’t ship a plugin yet. It settles how the plugins get written: in Rust, with the Proxy-Wasm Rust SDK, the same one Envoy plugins use.

The question was speed. The first test plugin was written in Go, and a Go plugin carries Go’s runtime into every call. So a Rust test plugin now does everything the Go one does, and the plugin host’s tests run with both on every push. The real SDK worked with the host as it was.
