P3 Request body seems unexpected

[itowlson]

I am writing a P3 handler using spin_sdk::http_wasip3::Request (not the IncomingRequest type used in the P3 double-echo example).

When I use the .body() method, I get a... thing... (&IncomingBody<Request>) which does not seem to let me access the body, but does let me access, say, the headers:

How do I get a body out of an IncomingBody<Request>? My specific interest is in processing the streaming body so I'm ultimately looking for a Stream or AsyncRead or something like that.

The incantation

use spin_sdk::http_wasip3::wasip3::http_compat::IncomingMessage;

unlocks consume_body().

For stable release it would be good to make this more expected, or at least to document it to the point of "oh that makes sense."

ETA: It would be good to generally cover off when and why to use Request vs IncomingRequest vs http::Request because I at least always feel like that I am in that much-loved maze of twisty passages all alike.
