Struct Tolerance 

pub struct Tolerance(/* private fields */);

The tolerance carried by a single vertex, edge or face: the radius within which the entity is considered to lie.

Always finite and non-negative. Operations may only widen it (see Tolerance::widen) because narrowing a tolerance asserts an accuracy the geometry does not have.

Implementations

impl Tolerance

pub const MIN: Self

The smallest meaningful tolerance, at unit scale.

pub fn new(value: f64) -> OgeomResult<Self>

A tolerance of value, clamped up to Tolerance::MIN.

Errors

OgeomError::Construction if value is not finite or is negative. A NaN tolerance poisons every comparison it reaches, so it is rejected at the boundary rather than propagated.

pub const fn get(self) -> f64

The tolerance as a length.

pub fn widen(self, other: Self) -> Self

This tolerance widened to at least other.

The only sanctioned way to change a tolerance. Boolean operations grow tolerances as they go; nothing shrinks them.

pub fn widen_to(self, value: f64) -> Self

This tolerance widened to at least value, ignoring non-finite input.

pub fn covers(self, distance: f64) -> bool

Whether a separation of distance is within this tolerance.

Trait Implementations

impl Clone for Tolerance

fn clone(&self) -> Tolerance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Tolerance

impl Debug for Tolerance

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

Formats the value using the given formatter.

impl Default for Tolerance

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Tolerance

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

impl PartialOrd for Tolerance

fn partial_cmp(&self, other: &Tolerance) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
