Struct Groups 

pub struct Groups {
    pub sizes: Vec<usize>,
    /* private fields */
}

Positions group by group, ascending within each group, with the number in each group. Each buffer holds whole groups. The two classes of a slice of two keys take a buffer each, which into_buffers hands over without a copy. Other groups share one buffer. Positions are u32s.

Fields

sizes: Vec<usize>

The number of positions in each group.

Implementations

impl Groups

pub fn each(&self) -> impl Iterator<Item = &[u32]>

The positions of each group, one slice for each group in turn. An empty group gives an empty slice.

pub fn into_positions(self) -> Vec<u32>

Every position, group by group, in one buffer. Groups that share a buffer hand it over.

pub fn into_buffers(self) -> Vec<Vec<u32>>

The buffers of positions, without a copy: one for each class of a slice of two keys, or one holding every group.
