Error returned by bounded collection operations.

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.

TooFew

The collection has fewer elements than the required minimum.

Fields

min: usize

The required minimum number of elements.

actual: usize

The actual number of elements.

TooMany

The collection has more elements than the allowed maximum.

Fields

max: usize

The allowed maximum number of elements.

actual: usize

The actual number of elements.

InvalidBounds

The const generic bounds are invalid (MIN > MAX).

Fields

min: usize

The configured minimum bound.

max: usize

The configured maximum bound.

ZeroCapacity

A capacity of zero was requested where a positive capacity is required.

Duplicate

A duplicate key or element was supplied where uniqueness is required.

Trait Implementations

impl Clone for CollectionError

fn clone(&self) -> CollectionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CollectionError

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

Formats the value using the given formatter.

impl Display for CollectionError

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

Formats the value using the given formatter.

impl Eq for CollectionError

impl Error for CollectionError

Available on crate feature std only.

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 CollectionError

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