EnumeratedCursor is a cursor of pairs (n, x), where ns are consecutive Int values starting at zero, and xs are the elements of a Base cursor.

To create an instance of EnumeratedCursor, call enumerated() on a cursor. For example:

let base = try String.fetchCursor(db, sql: """
    SELECT 'foo' UNION ALL SELECT 'bar'
    """)
let cursor = base.enumerated()
while let (n, x) = cursor.next() {
    print("\(n): \(x)")
}
// Prints: "0: foo"
// Prints: "1: bar"
