The snowflake crate(not available on cargo currently) is an implement of twitter's snowflake algorithm written in rust. Currently it generate uuid as follows:
- 1 bit for unused sign bit
- 41 bits for milliseconds timestamp since
std::time::UNIX_EPOCH - 10 bits for generator id:
- 5 bits for datacenter id
- 5 bits for worker id in specific datacenter
- rest 12 bits for sequence id generated in the same timestamp at the generator
In fact, the bits of the each three information can be flow, as long as they can form a 64 bit that can be store in an i64
TODO:
- make the bits of information configurable
- make the codes more neat
- make the EPOCH time configurable
optimize the block time counting
