BufferStream doesn't have any concrete model in Capy or Corosio

[akrzemi1]

Concept BufferStream does not have any concrete model in Capy or Corosio. It looks ike adding it now is premature. Without a concrete implementation (type-erased wrapper isn't one) you cannot be sure if you got the concept right; if you got the failure communication right.

Did you mean BufferSource/BufferSink? They are used by https://github.com/cppalliance/http

I am sorry for a silly request, but could you show me the exact location of a class in http that models BufferSource? I have only found one occurrence of identifier pull in the declaration (https://github.com/cppalliance/http/blob/master/include/boost/http/parser.hpp#L525C5-L525C9) but no corresponding definition.
