Enum DatumTargetKind 

pub enum DatumTargetKind {
    Point,
    Line {
        length: f64,
    },
    Rectangle {
        length: f64,
        width: f64,
    },
    Circle {
        diameter: f64,
    },
}

Where a datum is actually contacted: the target a fixture touches it at.

A datum plane on a casting is not contacted over its whole face (it rests on three pads), and the drawing says so with targets: A1, A2, A3, each a point, a line or an area of stated size. The distinction matters to anything that inspects the part, because the datum it should establish is the one the targets define and not the nominal surface.

Variants

Point

A point contact.

Line

A line contact, of the stated length.

Fields

length: f64

How long the contact runs.

Rectangle

A rectangular area.

Fields

length: f64

Along the target’s own reference direction.

width: f64

Across it.

Circle

A circular area.

Fields

diameter: f64

The contact patch’s diameter.

Trait Implementations

impl Clone for DatumTargetKind

fn clone(&self) -> DatumTargetKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DatumTargetKind

impl Debug for DatumTargetKind

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

Formats the value using the given formatter.

impl PartialEq for DatumTargetKind

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