函数

func S

1
func S(data ...[]byte) string

S creates and returns a global unique string in 32 bytes that meets most common usages without strict UUID algorithm. It returns a unique string using default unique algorithm if no data is given.

​ S 创建并返回一个 32 字节的全局唯一字符串,该字符串满足大多数常见用法,无需严格的 UUID 算法。如果给出 no data ,则使用默认的唯一算法返回一个唯一的字符串。

The specified data can be no more than 2 parts. No matter how long each of the data size is, each of them will be hashed into 7 bytes as part of the result. If given data parts is less than 2, the leftover size of the result bytes will be token by random string.

​ 指定的 data 不能超过 2 个部分。无论每个 data 大小有多长,它们中的每一个都将作为结果的一部分被哈希为 7 个字节。如果给定 data 的部分小于 2,则结果字节的剩余大小将由随机字符串标记。

The returned string is composed with: 1. Default: MACHash(7) + PID(4) + TimestampNano(12) + Sequence(3) + RandomString(6) 2. CustomData: DataHash(7/14) + TimestampNano(12) + Sequence(3) + RandomString(3/10)

​ 返回的字符串由以下部分组成: 1. 默认值:MACHash(7) + PID(4) + TimestampNano(12) + Sequence(3) + RandomString(6) 2.自定义数据:DataHash(7/14) + TimestampNano(12) + Sequence(3) + RandomString(3/10)

Note that:

​ 请注意:

  1. The returned length is fixed to 32 bytes for performance purpose. 出于性能目的,返回的长度固定为 32 字节。
  2. The custom parameter data composed should have unique attribute in your business scenario. data 编写的自定义参数在业务场景中应具有唯一属性。
