Topological Errors

Variants

SameVertex

Two same vertices cannot construct an edge.

Examples

use truck_topology::*;
use truck_topology::errors::Error;
let v = Vertex::new(());
assert_eq!(Edge::try_new(&v, &v, ()), Err(Error::SameVertex));

EmptyWire

The empty wire cannot contruct a face.

Examples

use truck_topology::*;
use truck_topology::errors::Error;
assert_eq!(Face::try_new(vec![Wire::<(), ()>::new()], ()), Err(Error::EmptyWire));

NotClosedWire

The boundary of a face must be closed.

Examples

use truck_topology::*;
use truck_topology::errors::Error;
let v = Vertex::news(&[(), ()]);
let wire: Wire<(), ()> = vec![Edge::new(&v[0], &v[1], ())].into();
assert_eq!(Face::try_new(vec![wire], ()), Err(Error::NotClosedWire));

NotSimpleWire

The boundary of a face must be simple.

Examples

use truck_topology::*;
use truck_topology::errors::Error;
let v = Vertex::news(&[(); 4]);
let wire: Wire<(), ()> = vec![
    Edge::new(&v[0], &v[1], ()),
    Edge::new(&v[1], &v[2], ()),
    Edge::new(&v[2], &v[3], ()),
    Edge::new(&v[3], &v[1], ()),
    Edge::new(&v[1], &v[0], ()),
].into();
assert_eq!(Face::try_new(vec![wire], ()), Err(Error::NotSimpleWire));

NotDisjointWires

Some boundaries has a shared vertex.

EmptyShell

The empty shell cannot construct a solid.

Examples

use truck_topology::*;
use truck_topology::errors::Error;
assert_eq!(Solid::try_new(vec![Shell::<(), (), ()>::new()]), Err(Error::EmptyShell));

NotConnected

The vector of boundaries of the solid must consist connected shells.

Examples

use truck_topology::*;
use truck_topology::errors::Error;
let v = Vertex::news(&[(), (), (), ()]);
let wire = vec![
    Wire::from(vec![Edge::new(&v[0], &v[1], ()), Edge::new(&v[1], &v[0], ())]),
    Wire::from(vec![Edge::new(&v[2], &v[3], ()), Edge::new(&v[3], &v[2], ())]),
];
let shell: Shell<(), (), ()> = wire.into_iter().map(|w| Face::new(vec![w], ())).collect();
assert_eq!(Solid::try_new(vec![shell]), Err(Error::NotConnected));

NotClosedShell

The boundary of the solid must be closed.

Examples

use truck_topology::*;
use truck_topology::errors::Error;
let v = Vertex::news(&[(), ()]);
let wire = Wire::from(vec![Edge::new(&v[0], &v[1], ()), Edge::new(&v[1], &v[0], ())]);
let shell: Shell<(), (), ()> = vec![Face::new(vec![wire], ())].into();
assert_eq!(Solid::try_new(vec![shell]), Err(Error::NotClosedShell));

NotManifold

The boundary of the solid must be a manifold.

Examples

// the wedge sum of two spheres
use truck_topology::*;
use truck_topology::errors::Error;
use std::iter::FromIterator;
let v = Vertex::news(&[(), (), ()]);
let edge = [
    Edge::new(&v[0], &v[1], ()),
    Edge::new(&v[1], &v[0], ()),
    Edge::new(&v[1], &v[2], ()),
    Edge::new(&v[2], &v[1], ()),
];
let wire = vec![
    Wire::from_iter(vec![&edge[0], &edge[1]]),
    Wire::from_iter(vec![&edge[1].inverse(), &edge[0].inverse()]),
    Wire::from_iter(vec![&edge[2], &edge[3]]),
    Wire::from_iter(vec![&edge[3].inverse(), &edge[2].inverse()]),
];
let shell: Shell<(), (), ()> = wire.into_iter().map(|w| Face::new(vec![w], ())).collect();
assert_eq!(Solid::try_new(vec![shell]), Err(Error::NotManifold));

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
