Struct ChunkView 

pub struct ChunkView {
    pub pos: ChunkPos,
    /* private fields */
}

Represents the set of all chunk positions that a client can see, defined by a center chunk position pos and view distance dist.

Fields

pos: ChunkPos

The center position of this chunk view.

Implementations

impl ChunkView

pub const fn new(pos: ChunkPos, dist: u8) -> ChunkView

Creates a new chunk view. dist is clamped to the range 0..MAX_VIEW_DIST.

pub const fn with_dist(self, dist: u8) -> ChunkView

pub const fn dist(self) -> u8

pub const fn contains(self, pos: ChunkPos) -> bool

pub fn iter(self) -> impl DoubleEndedIterator + ExactSizeIterator + Clone

Returns an iterator over all the chunk positions in this view. Positions are sorted by the distance to pos in ascending order.

pub fn diff(self, other: ChunkView) -> impl DoubleEndedIterator + Clone

Returns an iterator over all the chunk positions in self, excluding the positions that overlap with other. Positions are sorted by the distance to pos in ascending order.

pub fn bounding_box(self) -> (ChunkPos, ChunkPos)

Returns a (min, max) tuple describing the tight axis-aligned bounding box for this view. All chunk positions in the view are contained in the bounding box.

Examples

use chunkedge_server::{ChunkPos, ChunkView};

let view = ChunkView::new(ChunkPos::new(5, -4), 16);
let (min, max) = view.bounding_box();

for pos in view.iter() {
    assert!(pos.x >= min.x && pos.x <= max.x && pos.z >= min.z && pos.z <= max.z);
}

Trait Implementations

impl Clone for ChunkView

fn clone(&self) -> ChunkView

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkView

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

Formats the value using the given formatter.

impl Default for ChunkView

fn default() -> ChunkView

Returns the “default value” for a type.

impl PartialEq for ChunkView

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