No http.ServeStream() ?

[Liam]

Wondering why there's no http.ServeStream() API to do chunked transfer-encoding (or the http2 equivalent), in addition to the nice features of ServeContent()...

Has it been considered? Does it merit a proposal?

If not, some example code in the docs would be helpful...

Maybe because the current ServeHTTP does the chunked transfer-encoding when Content-Length is not set, and the Writes are more than the predefined buffer length?

Uh-huh. It would be nice to be able to use the If-None-Match logic for
unseekable strings.

I could be wrong, but I think that the Content-Length is always known in
ServeContent:

size, err := content.Seek(0, io.SeekEnd)
if err != nil {
return 0, errSeeker
}
