Trait SetOperand 

pub trait SetOperand<Other> {
    type Combined;
}

The marker of a compound query (UNION, INTERSECT, EXCEPT) built from a query with marker Self and an operand with marker Other.

The compound decodes like the left query. The operand’s sources are kept so the compound is scope-checked as a whole.

Required Associated Types

type Combined

The marker of the compound query.

Dyn Compatibility

This trait is dyn compatible.

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