### Compute CRC32 Checksum - Rust

Source: https://github.com/srijs/rust-crc32fast/blob/master/README.md

Computes the CRC32 checksum for a given byte slice using the convenience `hash` function. This is a simple way to get a checksum without managing a hasher instance.

```rust
let checksum = crc32fast::hash(b"foo bar baz");
```

### Advanced CRC32 Hashing - Rust

Source: https://github.com/srijs/rust-crc32fast/blob/master/README.md

Demonstrates advanced CRC32 hashing using the `Hasher` struct for more flexibility and performance, especially with large data. It involves creating a hasher, updating it with data, and finalizing to get the checksum.

```rust
use crc32fast::Hasher;

let mut hasher = Hasher::new();
hasher.update(b"foo bar baz");
let checksum = hasher.finalize();
```
