实例方法
elements
elementsEqual(_:)
返回一个布尔值,指示此序列和另一个序列是否包含相同顺序的相同元素。
声明
func elementsEqual<OtherSequence>(_ other: OtherSequence) -> Bool where OtherSequence : Sequence, Self.Element == OtherSequence.Element
当
Element
符合 Equatable
时可用。返回值
true
如果此序列和 other
包含以相同顺序的相同元素。
参数
other
要与此序列进行比较的序列。
详述
至少有一个序列必须是有限的。
此示例测试一个可数范围是否与另一个可数范围和数组共享相同的元素。
let a = 1...3
let b = 1...10
print(a.elementsEqual(b))
// Prints "false"
print(a.elementsEqual([1, 2, 3]))
// Prints "true"
