# CRC64

A 5-line\* CRC64 implementation in Rust.

\*: Yes, I cheated *a bit*. It is [antirez](https://github.com/antirez)' implementation of the [CRC64 algorithm for Redis][crc64.c], which basically consists of one huge table. See [lib.rs](src/crc64/lib.rs) for the exact constants used.

## Build

```
cargo build --release
```

## Usage

As a library:

```rust
use crc64::crc64;
crc64::crc64(0, "123456789".as_bytes());
```

As a standalone application:

```
$ ./target/release/crc64 src/crc64/lib.rs
```

## Tests

Run tests with:

```
cargo test
```
