Struct ranagrams::util::CharCount

pub struct CharCount {
    pub counts: Vec<usize>,
    pub sum: usize,
    pub first: usize,
    pub last: usize,
    // some fields omitted
}

The fundamental representation of the undigested bit of a phrase in anagram calculation, a CharCount keeps track of the characters still looking for a foster word. To accelerate processing, they also cache the first character offset with a non-zero count, the last such offset, the sum of their counts, and a checksum sufficient for hashing and identification.

Fields

counts: Vec<usize>

sum: usize

first: usize

last: usize

impl PartialEq<CharCount> for CharCount

pub fn eq(&self, other: &CharCount) -> bool
