pub trait AsQuery { type SqlType; type Query: Query<SqlType = Self::SqlType>; fn as_query(self) -> Self::Query; }
Expand description
Types that can be converted into a complete, typed SQL query.
This is used internally to automatically add the right select clause when
none is specified, or to automatically add RETURNING *
in certain contexts.
A type which implements this trait is guaranteed to be valid for execution.
