pub struct QueryItem { /* fields omitted */ }

Struct representing one AQL comparison in a Query.

Implementations

impl QueryItem

pub fn field(field_name: &str) -> QueryItemBuilder

Instantiates a new builder for a QueryItem with the specified field_name. The field will be used as the left value of the comparison.

Example

let query_item_builder = QueryItem::field("username");

pub fn all(array_field_name: &str) -> QueryItemBuilder

Instantiates a new builder for a QueryItem with the specified array_field_name. The field should be an array, as all items in the array will have to match the comparison to succeed.

Example

In this example the query will render all documents where every price is above 10.

Query::new(QueryItem::all("prices").greater_or_equal(10));

pub fn none(array_field_name: &str) -> QueryItemBuilder

Instantiates a new builder for a QueryItem with the specified array_field_name. The field should be an array, none of the items in the array can match the comparison to succeed.

Example

In this example the query will render all documents where every price is not above 10.

Query::new(QueryItem::none("prices").greater_or_equal(10));

pub fn any(array_field_name: &str) -> QueryItemBuilder

Instantiates a new builder for a QueryItem with the specified array_field_name. The field should be an array, at least one of the items in the array must match the comparison to succeed.

Example

In this example the query will render all documents where at least one price is above 10.

Query::new(QueryItem::any("prices").greater_or_equal(10));
