Trait scrapmetal::GenericQuery

pub trait GenericQuery<R> {
    fn query<T>(&mut self, t: &T) -> R
    where
        T: Term;
}

A similar work around as GenericTransform, but returning a query type, rather than the same type. This is roughly equivalent to for<T> FnMut(&T) -> R.

Required Methods

fn query<T>(&mut self, t: &T) -> R where
    T: Term, 

Call the query function on any T.

Implementors

• impl<Q, U, D, R> GenericQuery<R> for Query<Q, U, D, R> where
