Trait Implementations§

impl Clone for BasicByTag

source§

fn clone(&self) -> BasicByTag

Returns a copy of the value. Read more
1.0.0 · source§

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

source§

impl Debug for BasicByTag

source§

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

source§

impl MapReduce for BasicByTag

source§

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.
source§

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 BasicByTag

§

type Collection = Basic

The collection this view belongs to
§

type Key = String

The key for this view.
§

type Value = usize

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

fn name(&self) -> Name

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

fn view_name(&self) -> ViewName

impl ViewSchema for BasicByTag

§

type View = BasicByTag

The view this schema is defined for.

source§

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.
source§

fn version(&self) -> u64

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