Expand description

A collection of mappings and the associated documents.

Fields§

§mappings: Vec<CollectionMap<<<V as View>::Collection as Collection>::PrimaryKey, <V as View>::Key, <V as View>::Value>>

The collection of mappings.

§documents: BTreeMap<<<V as View>::Collection as Collection>::PrimaryKey, D>

All associated documents by ID.

Documents can appear in a mapping query multiple times. As a result, they are stored separately to avoid duplication.

Implementations§

source§

impl<D, V> MappedDocuments<D, V>where V: View,

source

pub fn len(&self) -> usize

The number of mappings contained in this collection.

source

pub fn is_empty(&self) -> bool

Returns true if there are no mappings in this collection.

source

pub fn get( &self, index: usize ) -> Option<MappedDocument<'_, D, <V as View>::Key, <V as View>::Value>>

Returns the mapped document atindex, or None if index >= self.len().

source

pub const fn iter(&self) -> MappedDocumentsIter<'_, D, V>

Returns an iterator over the contained mapped documents.
