Enum ChartInputError 

#[non_exhaustive]
pub enum ChartInputError {
    Sample {
        index: usize,
        error: ControlChartError,
    },
    TooFewSamples {
        got: usize,
        min: usize,
    },
    Standard(ControlChartError),
}

Why a chart computed from a whole slice of samples refused that slice.

Carries the position of the refused sample, which a sample-by-sample ControlChartError cannot: the chart functions that take every sample at once are the only place that position is known.

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.

Sample

The sample at index cannot be charted.

Fields

index: usize

Zero-based position of the sample in the input slice.

error: ControlChartError

What is wrong with it.

TooFewSamples

Fewer samples than the chart needs.

Fields

got: usize

Samples given.

min: usize

Samples required.

Standard(ControlChartError)

A known (Phase I) parameter given with the samples is invalid (ControlChartError::InvalidStandard).

Trait Implementations

impl Clone for ChartInputError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChartInputError

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

Formats the value using the given formatter.

impl Display for ChartInputError

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

Formats the value using the given formatter.

impl Error for ChartInputError

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.
