Enum EdgeName

pub enum EdgeName {
    Between(Box<FaceName>, Box<FaceName>),
    Anonymous(u32),
}

A persistent, structural name for one exact B-rep edge.

An edge is named by the faces that meet there rather than by its own arena slot, because that is what survives a rebuild: the intersection of two named faces is the same edge however the arenas are ordered.

Variants

Between(Box<FaceName>, Box<FaceName>)

The edge where two named faces meet.

The pair is stored in a canonical order so that naming the edge from either side produces the same name.

Anonymous(u32)

An edge whose provenance was not tracked by the producing operation.

Implementations

impl EdgeName

pub fn between(first: FaceName, second: FaceName) -> EdgeName

Name the edge shared by two faces, order-independently.

between(a, b) and between(b, a) are equal, because “the edge where these two faces meet” does not depend on which face is mentioned first. Without this an edge would have two names and a fillet applied from the other side would miss.

pub fn is_anonymous(&self) -> bool

Whether this name, or either face it names, is anonymous.

Trait Implementations

impl Clone for EdgeName

fn clone(&self) -> EdgeName

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeName

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

Formats the value using the given formatter.

impl Display for EdgeName

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

Formats the value using the given formatter.

impl Hash for EdgeName

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

where __H: Hasher,

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 EdgeName

fn cmp(&self, other: &EdgeName) -> 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 EdgeName

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

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