Enum DensityError 

#[non_exhaustive]
pub enum DensityError {
    KdTree(ErrorKind),
    EmptySample,
    EmptyNeighborhood,
}

Available on crate feature kde only.

Errors that can occur when estimating a density from a sample.

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.

KdTree(ErrorKind)

The k-d tree backing the nearest-neighbor search could not be built or queried.

EmptySample

The sample provided was empty, so no density can be estimated.

EmptyNeighborhood

No sample points fell within the queried neighborhood.

Trait Implementations

impl Debug for DensityError

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

Formats the value using the given formatter.

impl Display for DensityError

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

Formats the value using the given formatter.

impl Eq for DensityError

impl Error for DensityError

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 From<ErrorKind> for DensityError

fn from(err: ErrorKind) -> Self

Converts to this type from the input type.

impl PartialEq for DensityError

fn eq(&self, other: &DensityError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
