Struct toql_core::query::Wildcard

pub struct Wildcard { /* fields omitted */ }

A wildcard is used to select all fields from top or from a path.

Example

 let q = Query::new().and(Wildcard::new()).and(Wildcard::from("bar")); // more elegant -> Query::wildcard().and(...)

 assert_eq!("*, bar_*", q.to_string());

Note that the Toql derive builds a wildcard function too. If a struct Foo contained a struct Bar, it would be possible to replace the second call to and() with .and(Bar::fields().bar().wildcard())

pub fn new() -> Self

Creates a new wildcard to select all fields from top
