Enum DomainError 

pub enum DomainError {
    NotEnumerable,
    InvalidRange {
        min: String,
        max: String,
    },
    EmptyDiscrete,
    EmptySelection,
    ZeroMaxSelections,
}

Errors produced by domain constructors and operations.

Variants

NotEnumerable

The domain is not enumerable (continuous or open-ended). Returned by Domain::enumerate.

InvalidRange

A numeric range was rejected because min > max, a bound was NaN, or a bound was non-finite.

Fields

min: String

The rejected minimum bound as a display string.

max: String

The rejected maximum bound as a display string.

EmptyDiscrete

A discrete integer domain was constructed with zero values.

EmptySelection

A fixed selection domain was constructed with zero values.

ZeroMaxSelections

A selection domain was constructed with max_selections = 0.

Trait Implementations

impl Debug for DomainError

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

Formats the value using the given formatter.

impl Display for DomainError

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

Formats the value using the given formatter.

impl Error for DomainError

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<DomainError> for Error

fn from(source: DomainError) -> Self

Converts to this type from the input type.

impl PartialEq for DomainError

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