Struct google_firestore1_beta1::StructuredQuery

pub struct StructuredQuery {
    pub order_by: Option<Vec<Order>>,
    pub start_at: Option<Cursor>,
    pub end_at: Option<Cursor>,
    pub limit: Option<i32>,

}

A Firestore query.

This type is not used in any activity, and only used as part of another schema.

Fields

order_by: Option<Vec<Order>>

The order to apply to the query results.

Firestore guarantees a stable ordering through the following rules:

• Any field required to appear in order_by, that is not already specified in order_by, is appended to the order in field name order by default.
• If an order on __name__ is not specified, it is appended by default.

Fields are appended with the same sort direction as the last order specified, or 'ASCENDING' if no order was specified. For example:

• SELECT * FROM Foo ORDER BY A becomes SELECT * FROM Foo ORDER BY A, __name__
• SELECT * FROM Foo ORDER BY A DESC becomes SELECT * FROM Foo ORDER BY A DESC, __name__ DESC
• SELECT * FROM Foo WHERE A > 1 becomes SELECT * FROM Foo WHERE A > 1 ORDER BY A, __name__

start_at: Option<Cursor>

A starting point for the query results.

end_at: Option<Cursor>

A end point for the query results.

limit: Option<i32>

The maximum number of results to return.

Applies after all other constraints. Must be >= 0 if specified.

offset: Option<i32>

The number of results to skip.

Applies before limit, but after all other constraints. Must be >= 0 if specified.

from: Option<Vec<CollectionSelector>>

The collections to query.

where_: Option<Filter>

The filter to apply.

select: Option<Projection>

The projection to return.
