Struct FrequentItemset 

pub struct FrequentItemset { /* private fields */ }

A frequent itemset and its support over the transaction matrix.

items is the set of item (column) indices in ascending order; support is the fraction of transactions that contain every item in the set, in [0, 1].

Implementations

impl FrequentItemset

pub fn items(&self) -> &[usize]

The item indices forming this set, in ascending order.

pub const fn support(&self) -> f64

The support of this set (fraction of transactions containing every item).

Trait Implementations

impl Clone for FrequentItemset

fn clone(&self) -> FrequentItemset

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FrequentItemset

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FrequentItemset

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
