Message.V1Sourcetype t = | Graph_info of Bonsai.Private.Graph_info.Stable.V1.t| Performance_measure of Entry.V1.tinclude Core.Bin_prot.Binable.S with type t := tinclude Bin_prot.Binable.S_only_functions with type t := tThis function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.
