init<BaseIndex>(_ base: BaseIndex) where BaseIndex : Comparable
Creates a new index wrapping base
.
static func < (lhs: AnyIndex, rhs: AnyIndex) -> Bool
Returns a Boolean value indicating whether the first argument represents a position before the second argument.
static func == (lhs: AnyIndex, rhs: AnyIndex) -> Bool
Returns a Boolean value indicating whether two indices wrap equal underlying indices.
static func != (lhs: Self, rhs: Self) -> Bool
Returns a Boolean value indicating whether two values are not equal.
static func ... (minimum: Self) -> PartialRangeFrom<Self>
Returns a partial range extending upward from a lower bound.
static func ... (maximum: Self) -> PartialRangeThrough<Self>
Returns a partial range up to, and including, its upper bound.
static func ... (minimum: Self, maximum: Self) -> ClosedRange<Self>
Returns a closed range that contains both of its bounds.
static func ..< (maximum: Self) -> PartialRangeUpTo<Self>
Returns a partial range up to, but not including, its upper bound.
static func ..< (minimum: Self, maximum: Self) -> Range<Self>
Returns a half-open range that contains its lower bound but not its upper bound.
static func <= (lhs: Self, rhs: Self) -> Bool
Returns a Boolean value indicating whether the value of the first argument is less than or equal to that of the second argument.
static func > (lhs: Self, rhs: Self) -> Bool
Returns a Boolean value indicating whether the value of the first argument is greater than that of the second argument.
static func >= (lhs: Self, rhs: Self) -> Bool
Returns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument.
