## Usage

Add this to your Cargo.toml:

```toml
[dependencies]
bit-set = "0.5"
```

Since Rust 2018, `extern crate` is no longer mandatory. If your edition is old (Rust 2015),
add this to your crate root:

```rust
extern crate bit_set;
```

If you want to use bit-set in a program that has `#![no_std]`, just drop default features:

```toml
[dependencies]
bit-set = { version = "0.5", default-features = false }
```

<!-- cargo-rdme start -->

### Description

An implementation of a set using a bit vector as an underlying
representation for holding unsigned numerical elements.

It should also be noted that the amount of storage necessary for holding a
set of objects is proportional to the maximum of the objects when viewed
as a `usize`.

### Examples

```rust
use bit_set::BitSet;

// It's a regular set
let mut s = BitSet::new();
s.insert(0);
s.insert(3);
s.insert(7);

s.remove(7);

if !s.contains(7) {
    println!("There is no 7");
}

// Can initialize from a `BitVec`
let other = BitSet::from_bytes(&[0b11010000]);

s.union_with(&other);

// Print 0, 1, 3 in some order
for x in s.iter() {
    println!("{}", x);
}

// Can convert back to a `BitVec`
let bv = s.into_bit_vec();
assert!(bv[3]);
```
