source · pub struct Frequencies<T> { /* private fields */ }
Expand description
A commutative data structure for exact frequency counts.
Implementations§
source§impl<T: Eq + Hash> Frequencies<T>
impl<T: Eq + Hash> Frequencies<T>
sourcepub fn new() -> Frequencies<T>
pub fn new() -> Frequencies<T>
Create a new frequency table with no samples.
sourcepub fn cardinality(&self) -> u64
pub fn cardinality(&self) -> u64
Return the cardinality (number of unique elements) in the data.
sourcepub fn most_frequent(&self) -> Vec<(&T, u64)>
pub fn most_frequent(&self) -> Vec<(&T, u64)>
Return a Vec
of elements and their corresponding counts in
descending order.
sourcepub fn least_frequent(&self) -> Vec<(&T, u64)>
pub fn least_frequent(&self) -> Vec<(&T, u64)>
Return a Vec
of elements and their corresponding counts in
ascending order.
