Version

OS: macOS 15
Client: v3.7.0

Minimal reproduce step

Should be reproducible with any build attempt using Protobuf 30.0 (C++ 6.30.0) or later, at least when Abseil was built to use std::string_view.

However, won't be able to use Vcpkg build yet as they only have Protobuf 29.3 (C++ 5.29.3).

What did you expect to see?

Successful build

What did you see instead?

lib/ProtobufNativeSchema.cc:42:23: error: no viable conversion from 'internal::DescriptorStringView' (aka 'basic_string_view<char>') to 'const std::string' (aka 'const basic_string<char>')
   42 |     const std::string rootMessageTypeName = descriptor->full_name();
      |                       ^                     ~~~~~~~~~~~~~~~~~~~~~~~

Anything else?

Caused by breaking change in protocolbuffers/protobuf@d1990d9

Should be possible to use explicit constructor for std::string instead and work for both Protobuf 30 and older compatibility. I think move constructor/assignment should avoid unnecessary copies for older Protobuf.

Are you willing to submit a PR?
