protocol CopyableA type whose values can be implicitly or explicitly copied.
protocol Cursor<Element> : AnyObjectA type that supplies the values of some external resource, one at a time.
protocol Escapablefunc next() throws -> Statement? var isEmpty: Bool { get throws }Returns a Boolean value indicating whether the cursor does not contain any element.
func compactMap<ElementOfResult>(_ transform: @escaping (Element) throws -> ElementOfResult?) -> MapCursor<FilterCursor<MapCursor<Self, ElementOfResult?>>, ElementOfResult> Returns a cursor over the concatenated non-nil results of mapping transform over this cursor.
func contains(where predicate: (Element) throws -> Bool) throws -> Bool Returns a Boolean value indicating whether the cursor contains an element that satisfies the given predicate.
func drop(while predicate: @escaping (Element) throws -> Bool) -> DropWhileCursor<Self> Returns a cursor that skips any initial elements that satisfy predicate.
func dropFirst() -> DropFirstCursor<Self> Returns a cursor containing all but the first element of the cursor.
func dropFirst(_ n: Int) -> DropFirstCursor<Self> Returns a cursor containing all but the given number of initial elements.
func dropLast() throws -> [Element] Returns an array containing all but the last element of the cursor.
func dropLast(_ n: Int) throws -> [Element] Returns an array containing all but the given number of final elements.
func enumerated() -> EnumeratedCursor<Self> Returns a cursor of pairs (n, x), where n represents a consecutive integer starting at zero, and x represents an element of the cursor.
func filter(_ isIncluded: @escaping (Element) throws -> Bool) -> FilterCursor<Self> Returns the elements of the cursor that satisfy the given predicate.
func first(where predicate: (Element) throws -> Bool) throws -> Element? Returns the first element of the cursor that satisfies the given predicate or nil if no such element is found.
