Enum CircleConstructionError 

pub enum CircleConstructionError {
    NegativeRadius,
    NullNormal,
    ConfusedPoints,
    CollinearPoints,
    NonFinite,
}

Error returned when a Circle or Circle2D cannot be constructed from the given inputs.

Variants

NegativeRadius

The requested radius is negative.

NullNormal

The normal (or main axis direction) has zero length.

ConfusedPoints

Two (or more) of the three points given to build the circle are coincident (or too close to distinguish).

CollinearPoints

The three points given to build the circle are collinear, so no (finite-radius) circle passes through all three.

NonFinite

An input coordinate, radius, or angle is NaN or infinite.

impl Eq for CircleConstructionError

impl Error for CircleConstructionError

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
