Struct BlockRange 

pub struct BlockRange {
    pub parent: Vec<usize>,
    pub start: usize,
    pub end: usize,
}

A contiguous run of sibling blocks [start, end) under a common parent.

Fields

parent: Vec<usize>

Index-path to the shared parent node.

start: usize

First child index (inclusive).

end: usize

One-past-last child index (exclusive).

Implementations

impl BlockRange

pub fn new(parent: Vec<usize>, start: usize, end: usize) -> Self

Construct a range.

pub fn single(path: &[usize]) -> Self

The single-block range for a node path (parent = path[..n-1], the run [i, i+1)). An empty path yields an empty range at the root.

pub fn len(&self) -> usize

Number of blocks in the run.

pub fn is_empty(&self) -> bool

Whether the run is empty.

Trait Implementations

impl Clone for BlockRange

fn clone(&self) -> BlockRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockRange

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

Formats the value using the given formatter.

impl PartialEq for BlockRange

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