Struct QueryAnd

pub struct QueryAnd<Q1, Q2>where
    Q1: Query,
    Q2: Query,
{ /* private fields */ }

Expand description

Helper utility for combining two queries, useful if you want to iteratively construct a query in multiple parts.

Example:

use ixa::{define_person_property, people::QueryAnd, Context, ContextPeopleExt};
define_person_property!(Age, u8);
define_person_property!(Alive, bool);
let context = Context::new();
let q1 = (Age, 42);
let q2 = (Alive, true);
context.query_people(QueryAnd::new(q1, q2));
