Enum Error 

pub enum Error {
    EmptyPoints,
    TooManyPoints(usize),
    ShapeMismatch(usize, usize),
    BadWeight(usize),
}

An error-type for creating clustering-problems.

Variants

EmptyPoints

No points were supplied.

TooManyPoints(usize)

The number of points in the problem is too large. It must not exceed MAX_POINT_COUNT.

ShapeMismatch(usize, usize)

Two points (specified by their indices in the points-vec) have different dimensions.

BadWeight(usize)

A point’s (specified by its index in the points-vec) weight is non-finite or non-positive.

Positive infinity is not allowed to avoid degenerate cases for multiple +∞-points in the same cluster: If we have {(+∞, x), (+∞, y)} with x!=y, then we can reasonably set the cost to +∞. But if x==y, should the cost still be +∞, or should it be 0? +∞ * 0.0 is NaN.

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

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 Error

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