Struct Tolerance 

pub struct Tolerance<'m> { /* private fields */ }

A geometric tolerance (GEOMETRIC_TOLERANCE and its subtypes) — its characteristic kind, name, and nominal magnitude.

Implementations

impl<'m> Tolerance<'m>

pub fn kind(&self) -> ToleranceKind

The GD&T characteristic this tolerance specifies.

pub fn key(&self) -> EntityKey

This tolerance’s global identity (a Copy key for maps / dedup).

impl<'m> Tolerance<'m>

pub fn name(&self) -> &'m str

The tolerance’s name.

pub fn magnitude(&self) -> Option<f64>

The nominal magnitude (the tolerance-zone size).

The number is raw, in the model’s length unit — interpret it via Scene::units, exactly as point coordinates and dimension values are read. None when the tolerance carries no magnitude, or its magnitude is a complex measure instance the walk cannot resolve (reported via Scene::warnings).

impl<'m> Tolerance<'m>

pub fn datums(&self) -> Vec<Datum<'m>>

The datum reference frame this tolerance is controlled against, in precedence order (primary → secondary → tertiary).

Empty for a form tolerance (flatness, straightness, …) that references no datum. A common datum (A-B) is flattened to its constituent datums; a reference the walk cannot resolve (a complex facet) is reported via Scene::warnings.

impl<'m> Tolerance<'m>

pub fn feature(&self) -> Option<Feature<'m>>

The shape feature this tolerance applies to (its toleranced_shape_aspect).

None when the target is not a named shape aspect — a tolerance placed on a dimension or on the whole part (PRODUCT_DEFINITION_SHAPE) — or when the target is a complex instance the walk cannot resolve (reported via Scene::warnings).

Trait Implementations

impl<'m> Clone for Tolerance<'m>

fn clone(&self) -> Tolerance<'m>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'m> Copy for Tolerance<'m>
