Enum StatisticsError 

pub enum StatisticsError {
    EmptyInput,
    InsufficientData {
        needed: usize,
        actual: usize,
    },
    TooManyValues {
        actual: usize,
    },
}

Errors returned by statistics helpers when the input cannot support the requested summary.

Variants

EmptyInput

The input slice was empty.

InsufficientData

The input slice does not contain enough values for the requested operation.

Fields

needed: usize

actual: usize

TooManyValues

The input slice is too large to convert its length into an exact f64 count.

Fields

actual: usize

Trait Implementations

impl Clone for StatisticsError

fn clone(&self) -> StatisticsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StatisticsError

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

Formats the value using the given formatter.

impl Display for StatisticsError

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

Formats the value using the given formatter.

impl Error for StatisticsError

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 StatisticsError

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