Character Frequency

A Rust library for counting character frequencies over multiple threads

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.
  • character_frequencies_w_case(text: &str,case:CaseSense) -> HashMap<char, usize> Same as character_frequencies() but with Case Sensitive counting
  • character_frequencies_with_n_threads_w_case(text: &str,case:CaseSense) -> HashMap<char, usize> Same as character_frequencies_with_n_threads() but with Case Sensitive counting

Enums

  • CaseSense::InsensitiveASCIIOnly - Converts ASCII characters to lowercase before counting. This is the default.
  • CaseSense::Insensitive - Converts all UTF8 characters to lowercase before counting. If the Unicode character's lowercase version is a string, not a character, it panics.
  • CaseSense::Sensitive - Doesn't convert any characters to lowercase before counting.

Example

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

use character_frequency::*;

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

println!("Character frequencies:");
for (character, frequency) in frequency_map {
    print!("\'{}\': {},", character, frequency);
}
//Character frequencies:
//'r': 1 'd': 1 'o': 2 '!': 1 ',': 1 ' ': 1 'e': 1 'h': 1 'w': 1 'l': 3

This does the same but with case sensitivity.

let frequency_map = character_frequencies_w_case("Hello WORLD",CaseSense::Sensitive);

println!("Character frequencies:");
for (character, frequency) in frequency_map {
    print!("\'{}\': {},", character, frequency);
}
//Character frequencies:
//'R': 1 'D': 1 'O': 1 'o': 1 ' ': 1 'e': 1 'H': 1 'W': 1 'l': 2 'L': 1
