Twitter snowflake worker - Twitter Snowflake ID Generator
The default Twitter format shown below.
- Default: 1-41-10(5-5)-12, time accurecy is millsecond
- Baidu-Generator: 1-28-22-13, time accurecy is second
- nodeBits = DatacenterBits + workerBits
import trellis.tech/trellis/common.v3/id/snowflake
// You can set your epoch time
// but do not set the time before 69 years ago, then you should get the overflowed number
worker, _ := snowflake.NewWorker() // below pow(2, nodeBits) = 1024
// get by for
id := worker.Next()
// get by sleep until Millisecond
id = worker.NextSleep()
