Jakob Buchgraber	976029283f	Implement Maps for strings This change implements maps with keys and values of type string e.g. Map<ProtoStr, i32> and Map<ProtoStr, ProtoStr>. Implementing the Map type for ProtoStr has been different from scalar types because ProtoStr is an unsized type i.e. its size is not known at compile time. The existing Map implementation assumed sized types in many places. To make unsized types fit into the existing code architecture I have added an associated type 'Value' to the MapWith*KeyOps traits. The associated type needs to be sized and is the type returned by the Map::get(self, key) method e.g. for aProtoStr, the `type Value = &ProtoStr`. PiperOrigin-RevId: 588783751	1 year ago
Jakob Buchgraber	001be3c655	Implement Maps for scalar types for the C++ kernel This CL implements Maps for scalar types for the C++ runtime. It's orthogonal to cl/580453646. This CL is constrained by having to force template instantiation of proto2::Map<K, V>. Put differently, a Rust protobuf::Map<K, V> implementation needs to call 'extern "C"' functions with both key and value type in the function name (e.g. __pb_rust_Map_i32_f64_get()). We use macros to generate a Map implementation for every (K,V)-pair. An alternative would have been to use vtables. Luckily a key in a protobuf map can only be integer types, bool and string. So the number of key types is bounded by the specification, while the number of value types is not i.e. any protobuf message can be a value in a map. Given these constraints we introduce one 'MapKeyOps' trait per key type e.g. MapKeyBOOLOps or MapKeyI32Ops. These traits need to be implemented for every value type e.g. 'impl MapKeyBOOLOps for i32' will implement 'Map::<bool, i32>'. In particular the MapKeyOps traits can also be implemented for generated messages without violating the orphan rule. This CL also contains significant changes to the UPB runtime so that both upb.rs and cpp.rs export a similar interface to simplify the implementation in map.rs and the generated code. This CL does not yet implement the Proxied trait. PiperOrigin-RevId: 582951914	1 year ago
