Struct Vspan 

pub struct Vspan {
    pub x: u32,
    pub y: u32,
    pub z0: u8,
    pub z1: u8,
}

One vertical span on a column: (x, y, z0..=z1) solid voxels.

z1 is INCLUSIVE per voxlap’s vspans convention — the actual edited range is the half-open [z0, z1 + 1). Same convention makes a Vspan { z0: 100, z1: 100 } carve / fill exactly one voxel at z=100.

x / y are full-world u32 coordinates (cleaner than voxlap’s 8-bit vspans.x + setspans offs trick — for our cave demo the patch-relative + offset machinery isn’t needed).

Fields

x: u32

y: u32

z0: u8

z1: u8

Trait Implementations

impl Clone for Vspan

fn clone(&self) -> Vspan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Vspan

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

Formats the value using the given formatter.

impl PartialEq for Vspan

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