Chars Counter

The trait that implements character counting for the &str type.

Quick Start

```rust use chars_counter::{ICharsCounter, ICharCounterExt};

let str = "Hello world!"; let result = str.count_chars(); // result = [CharsCounter { character: 'l', count: 3 }, CharsCounter { character: 'o', count: 2 }, CharsCounter { character: ' ', count: 1 }, CharsCounter { character: '!', count: 1 }, CharsCounter { character: 'H', count: 1 }, CharsCounter { character: 'd', count: 1 }, CharsCounter { character: 'e', count: 1 }, CharsCounter { character: 'r', count: 1 }, CharsCounter { character: 'w', count: 1 }]

// You can also use like this: let result = str.countcharsnumeric(); let result = str.countcharsalphabetic(); let result = str.countcharschinese(); // ...... Others you can try by yourself. // if those can't meet your needs, you can custom your own rules by let result = str.countcharsfilter(|x| *x != ' '); // ignore whitespaces.

// More features: let result = str.countchars().mostchars(); // result = [CharsCounter { character: 'l', count: 3 }] let result = str.countchars().leastchars(); // result = [CharsCounter { character: ' ', count: 1 }, CharsCounter { character: '!', count: 1 }, CharsCounter { character: 'H', count: 1 }, CharsCounter { character: 'd', count: 1 }, CharsCounter { character: 'e', count: 1 }, CharsCounter { character: 'r', count: 1 }, CharsCounter { character: 'w', count: 1 }] let result = str.countchars().findbychar('l'); // result = Some(CharsCounter { character: 'l', count: 3 }) let result = str.countchars().findbynum(2); // result = [CharsCounter { character: 'o', count: 2 }] let result = str.countchars().leastchars().findbychar('H'); // result = Some(CharsCounter { character: 'H', count: 1 }) ```
