An abstract collection data type.

By default returns [NotImplemented][E::NotImplemented] for every method.

Required Associated Types

type Element

The element type of the collection.

Provided Methods

fn collection_capacity(&self) -> Result<usize, NotAvailable>

Returns the reserved capacity for elements in the collection.

fn collection_len(&self) -> Result<usize, NotAvailable>

Returns the current number of elements in the collection.

fn collection_is_empty(&self) -> Result<bool, NotAvailable>

Returns true if the collection is empty, false if it’s not.

fn collection_is_full(&self) -> Result<bool, NotAvailable>

Returns true if the collection is full, false if it’s not.

fn collection_contains( &self, element: Self::Element, ) -> Result<bool, NotAvailable>

where Self::Element: PartialEq,

Returns true if the collection contains the given element.

fn collection_count( &self, element: &Self::Element, ) -> Result<usize, NotAvailable>

where Self::Element: PartialEq,

Counts the number of times a given element appears in the collection.

Implementations on Foreign Types

impl<T, const N: usize> DataCollection for [T; N]

fn collection_is_empty(&self) -> Result<bool, NotAvailable>

Returns [NotSupported][E::NotSupported] since a fixed-size array is never empty or full.

fn collection_is_full(&self) -> Result<bool, NotAvailable>

Returns [NotSupported][E::NotSupported] since a fixed-size array is never empty or full.
