Trait Implementations

impl Clone for BasicByParentId

fn clone(&self) -> BasicByParentId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BasicByParentId

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

Formats the value using the given formatter.

impl MapReduce for BasicByParentId

fn map<'doc>( &self, document: &'doc BorrowedDocument<'_> ) -> ViewMapResult<'doc, Self>

The map function for this view. This function is responsible for emitting entries for any documents that should be contained in this View. If None is returned, the View will not include the document. See the user guide’s chapter on views for more information on how map works.

fn reduce( &self, mappings: &[ViewMappedValue<'_, Self>], _rereduce: bool ) -> ReduceResult<Self::View>

Returns a value that is produced by reducing a list of mappings into a single value. If rereduce is true, the values contained in the mappings have already been reduced at least one time. If an error of ReduceUnimplemented is returned, queries that ask for a reduce operation will return an error. See the user guide’s chapter on views for more information on how reduce works.

impl View for BasicByParentId

type Collection = Basic

The collection this view belongs to

type Key = Option<u64>

The key for this view.

type Value = usize

An associated type that can be stored with each entry in the view.

fn name(&self) -> Name

The name of the view. Must be unique per collection.

fn view_name(&self) -> ViewName

The namespaced name of the view.

impl ViewSchema for BasicByParentId

type MappedKey<'doc> = <<BasicByParentId as ViewSchema>::View as View>::Key

The key type used during the map/reduce operation.

type View = BasicByParentId

The view this schema is defined for.

fn version(&self) -> u64

The version of the view. Changing this value will cause indexes to be rebuilt.

fn update_policy(&self) -> ViewUpdatePolicy

Returns the update policy for this view, which controls when and how the view’s data is updated. The provided implementation returns ViewUpdatePolicy::Lazy.

impl DefaultViewSerialization for BasicByParentId
