Enum IndexKeyError

    ZeroDimension {
        position: usize,
    },
    LengthMismatch {
        expected: usize,
        actual: usize,

    },
}

Failures from index-key construction and encoding.

Variants

ZeroDimension

A local dimension was zero, so the index space is empty.

Fields

position: usize

Position of the offending dimension.

LengthMismatch

A multi-index had the wrong number of components.

Fields

expected: usize

Number of local dimensions the indexer was built with.

actual: usize

Number of components supplied.

IndexOutOfRange

A component was not less than its local dimension.

Fields

position: usize

Position of the offending component.

value: usize

The supplied value.

dim: usize

The local dimension at that position.

WidthOverflow

The requested key width exceeds what this build can represent.

Fields

requested_bits: u64

Total bits requested.

Trait Implementations

impl Clone for IndexKeyError

fn clone(&self) -> IndexKeyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for IndexKeyError

impl Debug for IndexKeyError

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

Formats the value using the given formatter.

impl Display for IndexKeyError

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

Formats the value using the given formatter.

impl Eq for IndexKeyError

impl Error for IndexKeyError

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 IndexKeyError

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