## Usage
Add this to your Cargo.toml:
```toml
[dependencies]
bit-set = "0.8"
```
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 `serde`, enable it with the `serde` feature:
```toml
[dependencies]
bit-set = { version = "0.8", features = ["serde"] }
```
If you want to use bit-set in a program that has `#![no_std]`, just drop default features:
```toml
[dependencies]
bit-set = { version = "0.8", default-features = false }
```

### 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]);
```
