how to use @struct? about scala-native HOT 1 CLOSED

@scala.scalanative.runtime.struct is a legacy, experimental way of interacting with C-like structs. As the package name suggests it's private to the runtime. These can be only used as receivers e.g. to extract fields of struct value returned by the extern method.
There were plans to make these a 1st class citizens (#897 ), but this improvement was postponed due to multiple difficulties of working with structs. Notably the issue of passing structs by value in the C interop as well as issues of converting between reference and value of a struct.

The error shown above is a fallout of partial implementation of @struct - these do not define constructors.
Current, idiomatic, way of dealing with C-structs involves usage of anonymous unsafe.CStructN types and typically creating an extension methods for easier interaction with them. Sadly, it's currently the only way until we'd be able to introduce new FFI model.
