Struct Role 

pub struct Role(pub u32);

What an entity is, relative to the operation that made it.

The low values are shared vocabulary; everything from Role::OP_DEFINED up is interpreted by the producing operation alone. Keeping it a newtype rather than an enum avoids inventing a taxonomy of every role in a CAD kernel before we have written the operations that need one.

0: u32

Implementations

impl Role

pub const SOLE: Self

No distinguishing role: the operation produced exactly one entity of this kind, so it needs no further discriminator.

pub const OUTER: Self

The result’s outer boundary: the outer wire of a face, the outer shell of a solid.

pub const INNER: Self

An inner boundary: a hole.

pub const START_CAP: Self

The start of a swept or extruded result.

pub const END_CAP: Self

The end of a swept or extruded result.

pub const LATERAL: Self

The swept side wall between the caps.

pub const SEAM: Self

A seam on a closed surface.

pub const OP_DEFINED: u32 = 1024

The first value an operation may assign meaning to itself.

pub const fn op_defined(index: u32) -> Self

An operation-defined role. index is offset above Role::OP_DEFINED.

Trait Implementations

impl Clone for Role

fn clone(&self) -> Role

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Role

impl Debug for Role

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

Formats the value using the given formatter.

impl Eq for Role

impl Hash for Role

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Role

fn cmp(&self, other: &Role) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Role

fn eq(&self, other: &Role) -> 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 Role

fn partial_cmp(&self, other: &Role) -> 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.
