Struct rustc_mir::dataflow::lattice::Dual[−][src]

pub struct Dual<T>(pub T);
Expand description

The counterpart of a given semilattice T using the inverse order.

The dual of a join-semilattice is a meet-semilattice and vice versa. For example, the dual of a powerset has the empty set as its top element and the full set as its bottom element and uses set intersection as its join operator.
