Consulte la publicación de Don blog sobre este tema, específicamente la sección Igualdad personalizada y comparación.
El ejemplo que da es casi idéntica a la estructura de registro que se propone:
/// A type abbreviation indicating we’re using integers for unique stamps on objects
type stamp = int
/// A type containing a function that can’t be compared for equality
[<CustomEquality; CustomComparison>]
type MyThing =
{ Stamp: stamp;
Behaviour: (int -> int) }
override x.Equals(yobj) =
match yobj with
| :? MyThing as y -> (x.Stamp = y.Stamp)
| _ -> false
override x.GetHashCode() = hash x.Stamp
interface System.IComparable with
member x.CompareTo yobj =
match yobj with
| :? MyThing as y -> compare x.Stamp y.Stamp
| _ -> invalidArg "yobj" "cannot compare values of different types"
