Enum TriangulateError

pub enum TriangulateError {
    AlreadyTriangulated,
    NoEar,
    NonFannable,
    NotEnoughDarts(usize),
    TooManyDarts(usize),
    UndefinedFace(&'static str),
}

Error-modeling enum for triangulation routines.

Variants

AlreadyTriangulated

The face to triangulate is already a triangle.

NoEar

The face has no ear to use for triangulation using the ear clipping method.

NonFannable

The face is not fannable, i.e. there is no “star” vertex.

NotEnoughDarts(usize)

The number of darts passed to create the new segments is too low. The usize value is the number of missing darts.

TooManyDarts(usize)

The number of darts passed to create the new segments is too high. The usize value is the number of excess darts.

UndefinedFace(&'static str)

The face is not fit for triangulation. The String contains information about the reason.

Trait Implementations

impl Debug for TriangulateError

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

Formats the value using the given formatter.

impl Display for TriangulateError

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

Formats the value using the given formatter.

impl Error for TriangulateError

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for TriangulateError

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