Enum TangencyError

#[non_exhaustive]
pub enum TangencyError {
    NonFinite,
    InvalidRadius {
        index: usize,
        radius: Scalar,
    },
    ZeroDirection {
        index: usize,
    },
    Degenerate,
}

Why tangent_circles could not be solved.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NonFinite

A coordinate, direction or radius is not finite.

InvalidRadius

Constraint index is a circle whose radius is not positive.

Fields

index: usize

The constraint’s index (0, 1 or 2).

radius: Scalar

The radius given.

ZeroDirection

Constraint index is a line whose direction is shorter than the linear tolerance.

Fields

index: usize

The constraint’s index (0, 1 or 2).

Degenerate

Every sign choice’s elimination system was singular: the three constraints do not pin down a family of tangent circles (for example, three coincident points, three identical circles, or three parallel lines).

Trait Implementations

impl Clone for TangencyError

fn clone(&self) -> TangencyError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TangencyError

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

Formats the value using the given formatter.

impl Display for TangencyError

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

Formats the value using the given formatter.

impl Error for TangencyError

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 TangencyError

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