Google.Protobuf.Reflection.SymbolVisibility

public enum SymbolVisibility
Describes the 'visibility' of a symbol with respect to the proto import system. Symbols can only be imported when the visibility rules do not prevent it (ex: local symbols cannot be imported). Visibility modifiers can only set on `message` and `enum` as they are the only types available to be referenced from other files.
namespace Google.Protobuf.Reflection { public enum SymbolVisibility { [OriginalName("VISIBILITY_UNSET")] VisibilityUnset, [OriginalName("VISIBILITY_LOCAL")] VisibilityLocal, [OriginalName("VISIBILITY_EXPORT")] VisibilityExport } }
