Detect (class) records and struct records

[michael-damatov]

Currently, records are displayed as classes:

where ReSharper correctly shows them as a record

Similarly, record structs are displayed as simple structs:

the ReSharper correctly shows them as struct records:

To be done

• detect record classes and show them as record
  • consider not showing the class keyword for class records (or make this behavior configurable)
• try to detect record structs and show them as record struct (not trivial for imported libraries)
• consider not showing the IEquatable<T> interface as all records implement it implicitly (or make this behavior configurable)
