Struct NullRun 

pub struct NullRun {
    pub left: u64,
    pub height: u32,
}

One null collapse run of a single algorithm: the algorithm projects to the null constant across the aligned k-ary block [left, left + k^height).

This is the null subset of the general collapse run-extents — the only per-algorithm-divergent collapse, hence the minimal committed activation information. Non-null equal-value runs are mirrored across every algorithm’s tree and recovered from the shared data, so they are never tracked here.

Fields

left: u64

First leaf index of the null block.

height: u32

Height of the aligned k-ary null block; it spans arity^height leaves. height == 0 is a single inactive leaf.

Trait Implementations

impl Clone for NullRun

fn clone(&self) -> NullRun

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NullRun

impl Debug for NullRun

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

Formats the value using the given formatter.

impl Eq for NullRun

impl PartialEq for NullRun

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