js 中的原始实现:https://github.com/paralleldrive/cuid2
cuid2
是一种可能的全局唯一标识符替代方案,例如 UUID 等。 这种 ID 的长度是可配置的,并且可以更容易地手动复制粘贴。
这是一个 cuid2
的示例,具有其默认长度:lnapog2xtrbfatrw5qtrpvs6
。

请将此依赖项添加到您的 Package.swift
中以使用此库
.package(url: "https://github.com/RussBaz/cuid2.git", from: "0.0.1"),
然后将依赖项添加到目标中
.product(name: "cuid2", package: "cuid2"),
import cuid2
let id = createId() // quickest way to create a one off id
isCuid2(id: id) // to verify if the string can possibly be cuid2
// Alternatively, you can customise how the ids a generated
// by providing a custom session counter, cuid length and a custom fingerprint
func createId(counter: Cuid2SessionCounter? = nil, length: Int? = nil, fingerprint: String? = nil) -> String { }
// If you need to create many ids
// 1. please create an instance of the generator
struct Cuid2Generator {
// other code omitted
init(counter: Cuid2SessionCounter? = nil, length: Int? = nil, fingerprint: String? = nil) { }
// 2. and then use this method to create an array of ids
func generate(times: Int) -> [String] { }
// skipping more code
}
克隆存储库,从项目根目录使用 swift build -c release
构建发布版本。 cuid2cli
现在可以在 .build/<target-arch-platform>/release/
文件夹中使用。 将其移动或复制到目标位置。
