Trait AsQuery 

pub trait AsQuery<S> {
    // Required method
    fn into_query(self) -> Option<Query<S>>;
}

Anything that can become a query clause in scope S. A clause may be absent (into_query returns None) — that’s what makes an Option<Query<S>> a first-class optional filter.

Required Methods

fn into_query(self) -> Option<Query<S>>

The clause this produces, or None to contribute nothing.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
