Basic example
ⓘ
offer_mpst!( s, recv_mpst_a_from_d, { CBranchesAtoC::End(s) => { close_mpst_multi(s) }, CBranchesAtoC::Video(s) => { let (request, s) = recv_mpst_a_from_d(s)?; let s = send_mpst_a_to_b(request + 1, s); let (video, s) = recv_mpst_a_from_b(s)?; let s = send_mpst_a_to_d(video + 1, s); authenticator_recurs(s) }, } )?;
