#[non_exhaustive]pub struct StrQueryHelper<'query> { /* private fields */ }

only.Expand description
A helper type that allows printing out str slices
This type is necessary because it’s not possible
to cast from a reference of a unsized type like &str
to a reference of a trait object even if that
type implements all necessary traits
