Crate freqdist [−] [src]
Implementation of a Frequency Distribution in Rust. Keeps track of how many times an object appears in a larger context (for example, how many times a word appears in a piece of text). The underlying data structure of the Frequency Distribution is a HashMap, so the object that is being counted must be hashable.
Example
let mut fdist: FrequencyDistribution<&str> = FrequencyDistribution::new(); fdist.insert("hello"); fdist.insert("hello"); fdist.insert("goodbye"); assert_eq!(fdist.get(&"hello"), 2);
