How to get request size on server side from inside tower layer?

[gmossessian]

Is it possible to read the size in bytes of a tonic::codegen::http::Request<T>, or is the size only available once the inner prost::Message is consumed?

[LucioFranco]

Yeah, I don't think there is a way to peek at the header before its consumed by prost. You could always write a http body wrapper that tracks the bytes and reports them as it gets read from the buffer.
