# shannon-entropy

A rust library to calculate the Shannon entropy of a string.

# Usage

Available on crates.io

Add this to your Cargo.toml

```toml

[dependencies]

shannon-entropy = "0.2"

```

# Example

```rust

fn main() {

  let test_strings = vec![

                          ("hello world", 2.8453512),

                          ("hello worldd", 2.8553884),

                          ("a", 0.0),

                          ("", 0.0),

                          ];

  for (test, answer) in test_strings {

      let entropy: f32 = shannon_entropy(test);

      assert_eq!(entropy, answer);

  }  

}

```
