FirestoreSelectInitialBuilder

firestore::select_builder

Struct FirestoreSelectInitialBuilder 

Source 
pub struct FirestoreSelectInitialBuilder<'a, D>
where
    D: FirestoreQuerySupport + FirestoreGetByIdSupport + FirestoreListenSupport + FirestoreAggregatedQuerySupport + Clone + 'static,
{ /* private fields */ }
Expand description

The initial builder for a Firestore select/query operation.

Created by calling FirestoreExprBuilder::select(). This builder allows specifying initial query parameters like projections (fields to return) before defining the target collection or document IDs.

Implementations§

Source§

impl<'a, D> FirestoreSelectInitialBuilder<'a, D>
where D: FirestoreQuerySupport + FirestoreGetByIdSupport + FirestoreListenSupport + FirestoreAggregatedQuerySupport + Clone + Send + Sync + 'static,

Source

pub fn fields<I>(self, return_only_fields: I) -> Self
where I: IntoIterator, I::Item: AsRef<str>,

Specifies which fields of the documents should be returned by the query (projection).

If not set, all fields are returned.

§Arguments
  • return_only_fields: An iterator of field paths to return.
§Returns

The builder instance with the projection mask set.

Source

pub fn from<C>(self, collection: C) -> FirestoreSelectDocBuilder<'a, D>
where C: Into<FirestoreQueryCollection>,

Specifies the collection or collection group to query documents from.

§Arguments
  • collection: The ID of the collection or a FirestoreQueryCollection enum specifying a single collection or a collection group.
§Returns

A FirestoreSelectDocBuilder to further configure the query (filters, ordering, etc.).

Source

pub fn by_id_in(self, collection: &str) -> FirestoreSelectByIdBuilder<'a, D>

Specifies that documents should be fetched by their IDs from a specific collection.

§Arguments
  • collection: The ID of the collection where the documents reside.
§Returns

A FirestoreSelectByIdBuilder to specify the document IDs and other options.
