Struct CongruenceTolerance 

pub struct CongruenceTolerance { /* private fields */ }

A non-negative tolerance for congruence-style comparisons.

Implementations

impl CongruenceTolerance

pub const fn new(value: f64) -> Option<CongruenceTolerance>

Creates a finite, non-negative tolerance.

pub const fn value(self) -> f64

Returns the tolerance value.

pub fn matches_lengths(self, left: f64, right: f64) -> bool

Returns true when two lengths match within this tolerance.

Trait Implementations

impl Clone for CongruenceTolerance

fn clone(&self) -> CongruenceTolerance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CongruenceTolerance

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

Formats the value using the given formatter.

impl PartialEq for CongruenceTolerance

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