Enum Exact3Error 

pub enum Exact3Error {
    NonFiniteCoordinate {
        point: usize,
    },
    DegeneratePlane,
    ParallelToPlane,
}

Errors from exact 3-D construction. All fail-closed.

Variants

NonFiniteCoordinate

A supplied coordinate is not finite (NaN or ±∞). Exact construction is only defined over finite reals.

Fields

point: usize

Which point (0 = p, 1 = q, 2 = a, 3 = b, 4 = c).

DegeneratePlane

The plane is degenerate: (b − a) and (c − a) are parallel (or a point coincides), so a, b, c do not define a plane. The normal is the zero vector.

ParallelToPlane

The segment is parallel to the plane (den = n · (p − q) = 0), so there is no unique intersection point (the segment either misses the plane or lies entirely within it).

Trait Implementations

impl Clone for Exact3Error

fn clone(&self) -> Exact3Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Exact3Error

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

Formats the value using the given formatter.

impl Display for Exact3Error

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

Formats the value using the given formatter.

impl Error for Exact3Error

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 Exact3Error

fn eq(&self, other: &Exact3Error) -> 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.
