Struct IncidenceMatrix 

pub struct IncidenceMatrix { /* private fields */ }

A dense incidence matrix.

Implementations

impl IncidenceMatrix

pub fn new( point_count: usize, line_count: usize, entries: Vec<bool>, ) -> Option<Self>

Creates a dense incidence matrix when the entry count matches point_count * line_count.

pub const fn point_count(&self) -> usize

Returns the point count.

pub const fn line_count(&self) -> usize

Returns the line count.

pub fn is_incident(&self, point: usize, line: usize) -> Option<bool>

Returns whether a point is incident with a line.

Trait Implementations

impl Clone for IncidenceMatrix

fn clone(&self) -> IncidenceMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IncidenceMatrix

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

Formats the value using the given formatter.

impl PartialEq for IncidenceMatrix

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