Approximate Shannon Entropy

A rust library to calculate the approximate Shannon entropy of a slice.

Usable on no_std due to use of approximate natural log from micromath.

Usage

Add this to your Cargo.toml

[dependencies]
approx_shannon_entropy = "0.1.1"

Examples

$ cargo run --example three_bits
Shannon Entropy (approximate bits per byte): 1

$ cargo build --example stdin_entropy
$ echo A | ./target/debug/examples/stdin_entropy
