protocol Strideable Conforming types are notionally continuous, one-dimensional values that can be offset and measured. Inheritance Comparable, Equatable View Protocol Hierarchy → Associated Types Stride : SignedNumberType A type that can represent the distance between two values of Self. Import import Swift Instance Methods func <(_:rhs:) Required A strict total order over instances of Self. Declaration func <(lhs: Self, rhs: Self) -> Bool Declared In Comparable func <=(_:rhs:) Declaration func <=(lhs: Self, rhs: Self) -> Bool Declared In Comparable func ==(_:rhs:) Required Returns true if lhs is equal to rhs. Equality implies substitutability. When x == y, x and y are interchangeable in any code that only depends on their values. Class instance identity as distinguished by triple-equals === is notably not part of an instance's value. Exposing other non-value aspects of Equatable types is discouraged, and any that are exposed should be explicitly pointed out in documentation. Equality is an equivalence relation x == x is true x == y implies y == x x == y and y == z implies x == z Inequality is the inverse of equality, i.e. !(x == y) iff x != y. Declaration func ==(lhs: Self, rhs: Self) -> Bool Declared In Equatable func >(_:rhs:) Declaration func >(lhs: Self, rhs: Self) -> Bool Declared In Comparable func >=(_:rhs:) Declaration func >=(lhs: Self, rhs: Self) -> Bool Declared In Comparable func advancedBy(_:) Required Returns a Self x such that self.distanceTo(x) approximates n. Complexity: O(1). See Also: RandomAccessIndexType's advancedBy, which provides a stronger semantic guarantee. Declaration func advancedBy(n: Self.Stride) -> Self func distanceTo(_:) Required Returns a stride x such that self.advancedBy(x) approximates other. Complexity: O(1). See Also: RandomAccessIndexType's distanceTo, which provides a stronger semantic guarantee. Declaration func distanceTo(other: Self) -> Self.Stride Default Implementations func stride(through:by:) Returns the sequence of values (self, self + stride, self + stride + stride, ... last) where last is the last value in the progression less than or equal to end. Note: There is no guarantee that end is an element of the sequence. Declaration func stride(through end: Self, by stride: Self.Stride) -> StrideThrough<Self> func stride(to:by:) Returns the sequence of values (self, self + stride, self + stride + stride, ... last) where last is the last value in the progression that is less than end. Declaration func stride(to end: Self, by stride: Self.Stride) -> StrideTo<Self>
