pub struct OpportunisticVarResolver<'a, 'db> { /* private fields */ }Expand description
The opportunistic resolver can be used at any time. It simply replaces
type/const variables that have been unified with the things they have
been unified with (similar to shallow_resolve, but deep). This is
useful for printing messages etc but also required at various
points for correctness.
