Trait Implementations

impl Clone for ProjectBySlug

fn clone(&self) -> ProjectBySlug

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CollectionViewSchema for ProjectBySlug

type View = ProjectBySlug

The view this schema is an implementation of.

fn unique(&self) -> bool

If true, no two documents may emit the same key. Unique views are updated when the document is saved, allowing for this check to be done atomically. When a document is updated, all unique views will be updated, and if any of them fail, the document will not be allowed to update and an Error::UniqueKeyViolation will be returned.

fn version(&self) -> u64

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

fn map(&self, document: CollectionDocument<Project>) -> ViewMapResult<Self::View>

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.

fn lazy(&self) -> bool

Returns whether this view should be lazily updated. If true, views will be updated only when accessed. If false, views will be updated during the transaction that is updating the affected documents.

fn reduce(
    &self,
    mappings: &[MappedValue<<Self::View as View>::Key, <Self::View as View>::Value>],
    rereduce: bool
) -> Result<<Self::View as View>::Value, Error>

The reduce function for this view. If Err(Error::ReduceUnimplemented) is returned, queries that ask for a reduce operation will return an error. See CouchDB’s Reduce/Rereduce documentation for the design this implementation will be inspired by

impl Debug for ProjectBySlug

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

Formats the value using the given formatter.

impl View for ProjectBySlug

type Collection = Project

The collection this view belongs to

type Key = String

The key for this view.

type Value = ()

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.
