Struct Query 

pub struct Query {
    pub limit: Option<i64>,
    pub offset: Option<i64>,
    pub order_by: Vec<(String, String)>,
    pub filter: Option<Filter>,
    pub group: Option<String>,
    pub children: bool,
    pub fields: Option<Vec<String>>,
}

request.query for a list, and the filter that decides it.

request.query holds limit, offset and orderBy from here, and what the official emulator derives from the path (tools/oracle/rules_request_fields.py): kind, the collection ID (null for a query of every collection); parent, the document the collection is in (null at the root), named ancestor for a collection group; allDescendants; and distinct and selectOnlyKeys, always false, and groupBy, always empty, which Firestore queries cannot set.

Fields

limit: Option<i64>

offset: Option<i64>

order_by: Vec<(String, String)>

The orderings the query gives (not those completing it), field path to ASC or DESC, in the order request.query.orderBy lists them.

filter: Option<Filter>

group: Option<String>

For a collection group, its collection ID: the list covers the collections with that ID at any depth below Request::path (an empty ID: every collection below it).

children: bool

With an empty Query::group: only the collections directly below Request::path (a query whose from has no collection ID and is not allDescendants).

fields: Option<Vec<String>>

request.fields: the fields the query selects, as the official emulator lists them (None, null, without a projection).
