Character Frequency

A Rust library for counting character frequencies over multiple threads

Usage

Add this to your Cargo.toml:

[dependencies]
character_frequency = "0.1.0"

Functions

• character_frequencies(text: &str) -> HashMap<char, usize> Returns a map with the frequencies counted on the text parameter. It will run on as many threads as cpu's are available.
• character_frequencies_with_n_threads(text: &str, threads: usize) -> HashMap<char, usize>: Returns a map with the frequencies counted on the text parameter. It will run on the specified ammount of threads.

Example

This example counts the character frequencies of Hello, World! and print them afterwards:

use character_frequency::*;
use std::collections::HashMap;

let frequency_map = character_frequencies("Hello, World!");

println!("Character frequencies:");
for (character, frequency) in frequency_map {
    println!("\'{}\': {}", character, frequency);
}
