Struct ConstraintUsage 

pub struct ConstraintUsage {
    pub argument: usize,
    pub omit: bool,
}

What the module decided to do with one constraint.

Fields

argument: usize

The one-based position the value is passed to filter in, or zero when the constraint is not used.

omit: bool

Whether the engine may stop testing this constraint itself.

The module promising, not the engine assuming. A module that sets this and then does not apply the constraint returns wrong rows, which is why the default is to test it twice.
