I've got the following helper method in my project:
def close(c: Closeable) {
Option(c).foreach(s => Try(c.close))
}
I've got some classes that have a close method but do not implement Closeable. If I change the helper method to use structural types I can still use it on these classes:
def close(c: {def close()}) {
Option(c).foreach(s => Try(c.close))
}
However this introduces use of reflection which is something that I'd like to avoid in runtime.
Is there a way to use something similar to structural typing without inducing runtime reflection?
I.e in the same way Shapeless allows generic access to fields, maybe implicit parameters + macros could be used to access methods in the same way?
