# hyperid-rs [![Rust](https://github.com/allevo/hyperid-rs/actions/workflows/rust.yml/badge.svg?branch=main)](https://github.com/allevo/hyperid-rs/actions/workflows/rust.yml)
Superfast id generator

This is a porting of the amazing hyperid project written in [javascript](https://github.com/mcollina/hyperid).

## Install

Add the dependency to your `Cargo.toml`:
```toml
[dependencies]
hyperid = "2"
```

## Usage

```rust
use hyperid::HyperId;

fn main() {
    let mut hyperid = HyperId::default();

    // `generate` method returns a new id every time
    let id1 = hyperid.generate();
    let id2 = hyperid.generate();

    assert_ne!(id1, id2);

    // `get` method returns the last generated id
    let id3 = hyperid.get();

    assert_eq!(id2, id3);

    // Only if `url_safe` feature is enabled
    println!("{}", id1.to_url_safe()); // prints "3ZAYYJilG7vHTqiUuaQdFg.0"
}
```

## Benchmark
This crate borns for providing a fast id generator.
Comparing with uuid crates, on my computer:

```
$ cargo bench
...
test hyperid ... bench:           9 ns/iter (+/- 1)
test uuid    ... bench:       1,657 ns/iter (+/- 148)
...
```

## Features

This crate has a feature `url_safe` that adds `to_url_safe` and `from_url_safe` methods.

## Prepare for release

```sh
cargo release  -vv --skip-publish <version>
# wait for CI
git checkout <tag>
cargo publish
```
