Struct ComponentLabels

pub struct ComponentLabels { /* private fields */ }

Component identifiers for every cell of a mask.

Implementations

impl ComponentLabels

pub const fn count(&self) -> usize

Number of distinct components.

pub fn label(&self, x: usize, y: usize) -> Option<usize>

Component containing (x, y), or None for an unset or outside cell.

pub fn same_component(&self, from: (usize, usize), to: (usize, usize)) -> bool

Whether two cells share one component.

Trait Implementations

impl Clone for ComponentLabels

fn clone(&self) -> ComponentLabels

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentLabels

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

Formats the value using the given formatter.

impl PartialEq for ComponentLabels

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