如何消除静态方法与实现协议之间的歧义

Question

类型转换对于实例函数来说是很好的。

protocol Protocol1 {}
extension Protocol1 {
    func instanceFunc() {}
    static func staticFunc() {}
}
protocol Protocol2 {}
extension Protocol2 {
    func instanceFunc() {}
    static func staticFunc() {}
}
struct Struct: Protocol1, Protocol2 {
    func instanceFunc() {
        (self as Protocol1).instanceFunc()
        (self as Protocol2).instanceFunc()
    }
    static func staticFunc() {
        // My best guess. Nope!
        (Struct as Protocol1.Type).staticFunc()
        (Struct as Protocol2.Type).staticFunc()
    }
}

这应该能奏效，伙计

protocol Protocol1 {}
extension Protocol1 {
    func instanceFunc() {}
    static func staticFunc() {}
}
protocol Protocol2 {}
extension Protocol2 {
    func instanceFunc() {}
    static func staticFunc() {}
}
struct Struct: Protocol1, Protocol2 {
    func instanceFunc() {
        (self as Protocol1).instanceFunc()
        (self as Protocol2).instanceFunc()
    }
    static func staticFunc() {
        (Struct.self as Protocol1.Type).staticFunc()
        (Struct.self as Protocol2.Type).staticFunc()
    }
}
