        lengths: Vec<usize>,
    },
    TooManyConfigs,
    NoSamples,
    NoFactors,
    UnlistedLevels {

}

A block whose design cannot combine its factors.

Variants

UnequalLengths

A zip over factors with different numbers of levels.

Fields

lengths: Vec<usize>

Number of levels of each factor, in factor order.

TooManyConfigs

A design whose configs would take the plan past MAX_CONFIGS.

NoSamples

A random or Latin hypercube design of 0 samples.

NoFactors

A random or Latin hypercube design with no factor to draw.

UnlistedLevels

Factor factor_index of a factorial or zip design, a range with no listed levels.

Fields

factor_index: usize

Index of the factor in its block, counting from 0.

NoLevels

Factor factor_index, a list with no levels.

Fields

factor_index: usize

Index of the factor in its block, counting from 0.

Trait Implementations

impl Clone for DesignError

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 DesignError

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

Formats the value using the given formatter.

impl Display for DesignError

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

Formats the value using the given formatter.

impl Eq for DesignError

impl Error for DesignError

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 DesignError

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

Equality operator ==.

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

Inequality operator !=.
