Struct Grouped 

pub struct Grouped {
    pub k: usize,
}

Grouping is a k-fold over the groups, with the samples following theirs. Needs in_groups and takes no seed: it places the biggest groups first into whichever fold is emptiest, which is what keeps the folds comparable when the groups are not.

Fields

k: usize

How many folds.

Implementations

impl Grouped

pub fn folds(&self, samples: &Samples) -> Result<Vec<Fold>, PartitionError>

The folds, in order. Two samples with the same group never end up on opposite sides.

Trait Implementations

impl Clone for Grouped

fn clone(&self) -> Grouped

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Grouped

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

Formats the value using the given formatter.

impl Display for Grouped

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

Formats the value using the given formatter.

impl From<Grouped> for Partition

fn from(cut: Grouped) -> Self

Converts to this type from the input type.

impl Hash for Grouped

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Grouped

fn eq(&self, other: &Grouped) -> 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.
