c# - Protobuf-net asking for TypeModel.CS when used with Generics for deserialization -

i have billions of objects i'm trying construction them in b+tree serialized hdd. i'm using bplustree library info construction , protobuf-net serialization/deserialization. in regard define classes as:

[protocontract] public class b<c, m> c : icomparable<c> m : idata<c> { internal b() { lambda = new list<lambda<c, m>>(); omega = 0; } internal b(c coordinate) { lambda = new list<lambda<c, m>>(); e = coordinate; omega = 0; } [protomember(1)] internal c e { set; get; } [protomember(2)] internal list<lambda<c, m>> lambda { private set; get; } [protomember(3)] internal int omega { set; get; } } [protocontract] public class lambda<c, m> c : icomparable<c> m : idata<c> { internal lambda() { } internal lambda(char tau, m ati) { this.tau = tau; this.ati = ati; } [protomember(1)] internal char tau { private set; get; } [protomember(2)] internal m ati { private set; get; } }

and define serializers/deserializers following:

public class bserializer<c, m> : iserializer<b<c, m>> c : icomparable<c> m : idata<c> { public b<c, m> readfrom(system.io.stream stream) { homecoming serializer.deserialize<b<c, m>>(stream); } public void writeto(b<c, m> value, system.io.stream stream) { serializer.serialize<b<c, m>>(stream, value); } }

then utilize them in b+tree (this library) info construction defined as:

var options = new bplustree<c, b<c, m>>.optionsv2(cserializer, bserializer); var mytree = new bplustree<c, b<c, m>>(options);

the b+tree defined dictionary of key-value pairs. key (i.e., c) integer , serializer default serializer of bplustree library. value custom object b<c,m> serialized using protobuf-net.

my problem certainly happens, @ random times; searching keys, starts deserializing value , @ first phone call of b<c, m> readfrom(system.io.stream stream) asks typemodel.cs , protoreader.cs files. both packages nuget.

checking code, looks calling code assumes serializations aware of own length; source:

foreach (t in items) _serializer.writeto(i, io);

protobuf messages are not self-terminating - google protobuf specification defines append===merge. such, you'll need prefix messages. fortunately, should able switch serializewithlengthprefix , deserializewithlengthprefix. if doesn't work, worth putting reproducible illustration can investigated.
