# IdGenerator

A powerful unique id generator.

Inspired by yitter/IdGenerator. Please see it for original documentation on the option choice.

Shorter ID and faster generation with a new snowflake drift algorithm. The core is to shorten the ID length, but also can have a very high instantaneous concurrent processing capacity (50W/0.1s), and powerful configuration capacity.

If you want to have such a high throughput, please set a higher seq_bit_len (e.g. 10).

Also support for multiple worker_id in one instance, using HashMap or Vector. More usage examples please see tests in lib.rs or docs on docs.rs

DO NOT USE A MIXTURE OF THEM!

Simple Usage example

First, global initialize:

```rust use idgenerator::{IdHelper, IdGeneratorOptions}; // Create a instance IdHelper::init(); // Create IdGeneratorOptions, workerid is the only parameter needed: let mut options = IdGeneratorOptions::new(1); // If you want to have a larger workid range, set workeridbitlen to a larger number options.workeridbitlen = 8; // default to 8, meaning the max number of work_id is 2^8 - 1 // Other options can be seen in IdGeneratorOptions

// You must save parameters before generating IdHelper::setidgenerator(options); ```

Second, generate ID:

rust use idgenerator::IdHelper; // call next_id() at where you want to generate the ID let new_id: i64 = IdHelper::next_id(); println!("ID: {}", new_id);

More usage examples please see docs on docs.rs or mod.rs. Also can see the tests in lib.rs
