Struct Portion 

pub struct Portion { /* private fields */ }

The regions this instance touches and how much of the first and last is its own. Counted in the level below’s joint steps.

The steps are laid end to end and cut into one run an instance, every run ceil(steps / instances) long but the last that holds any, which holds what is left: the runs holding steps come first, so no run between two that hold steps is empty, and the longest run, which is what the level takes, is as short as an even split’s.

Implementations

impl Portion

pub fn touched(&self) -> usize

How many regions the portion touches.

pub fn region(&self, i: usize) -> Region

The i-th region the portion touches.

pub fn index(&self, i: usize) -> usize

The i-th region the portion touches, in the level’s flat index: one for every region of the level, whichever instance touches it.

pub fn steps(&self, i: usize) -> (usize, usize)

Start and length of this portion’s steps within the i-th region’s walk below.

pub fn holders(&self, i: usize) -> (usize, usize)

The first run holding steps of the i-th region the portion touches, and how many runs hold them. This run is one of them.

pub fn run(&self) -> usize

This instance’s run, counted from the first.

pub fn starts_in(&self, i: usize, run: usize) -> bool

Whether run, one of the holders of the i-th region the portion touches, starts there rather than in a region before it.

pub fn __expand_touched( scope: &Scope, this: &<Self as CubeType>::ExpandType, ) -> <usize as CubeType>::ExpandType

How many regions the portion touches.

pub fn __expand_region( scope: &Scope, this: &<Self as CubeType>::ExpandType, i: <usize as CubeType>::ExpandType, ) -> <Region as CubeType>::ExpandType

The i-th region the portion touches.

pub fn __expand_index( scope: &Scope, this: &<Self as CubeType>::ExpandType, i: <usize as CubeType>::ExpandType, ) -> <usize as CubeType>::ExpandType

The i-th region the portion touches, in the level’s flat index: one for every region of the level, whichever instance touches it.

pub fn __expand_steps( scope: &Scope, this: &<Self as CubeType>::ExpandType, i: <usize as CubeType>::ExpandType, ) -> (<usize as CubeType>::ExpandType, <usize as CubeType>::ExpandType)

Start and length of this portion’s steps within the i-th region’s walk below.

pub fn __expand_holders( scope: &Scope, this: &<Self as CubeType>::ExpandType, i: <usize as CubeType>::ExpandType, ) -> (<usize as CubeType>::ExpandType, <usize as CubeType>::ExpandType)

The first run holding steps of the i-th region the portion touches, and how many runs hold them. This run is one of them.

pub fn __expand_run( scope: &Scope, this: &<Self as CubeType>::ExpandType, ) -> <usize as CubeType>::ExpandType

This instance’s run, counted from the first.

pub fn __expand_starts_in( scope: &Scope, this: &<Self as CubeType>::ExpandType, i: <usize as CubeType>::ExpandType, run: <usize as CubeType>::ExpandType, ) -> <bool as CubeType>::ExpandType

Whether run, one of the holders of the i-th region the portion touches, starts there rather than in a region before it.
