source · [−]

pub struct MappedDocuments<D, V: View> {
    pub mappings: Vec<Map<V::Key, V::Value>>,
    pub documents: BTreeMap<u64, D>,
}

Expand description

A collection of mappings and the associated documents.

Fields

mappings: Vec<Map<V::Key, V::Value>>

The collection of mappings.

documents: BTreeMap<u64, 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: View> MappedDocuments<D, V>

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::Key, V::Value>>

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