## Usage
```rust
use cid::multihash::{Code, MultihashDigest};
use cid::Cid;
use std::convert::TryFrom;
const RAW: u64 = 0x55;
fn main() {
let h = Code::Sha2_256.digest(b"beep boop");
let cid = Cid::new_v1(RAW, h);
let data = cid.to_bytes();
let out = Cid::try_from(data).unwrap();
assert_eq!(cid, out);
let cid_string = cid.to_string();
assert_eq!(
cid_string,
"bafkreieq5jui4j25lacwomsqgjeswwl3y5zcdrresptwgmfylxo2depppq"
);
println!("{}", cid_string);
}
```
Your `Cargo.toml` needs these dependencies:
```toml
[dependencies]
cid = "0.7.0"
```
You can also run this example from this checkout with `cargo run --example readme`.
