pub enum WherePredicate {
BoundPredicate(WhereBoundPredicate),
RegionPredicate(WhereRegionPredicate),
EqPredicate(WhereEqPredicate),
}
Expand description
A single predicate in a where-clause.
Variants§
BoundPredicate(WhereBoundPredicate)

).
EqPredicate(WhereEqPredicate)
An equality predicate (unsupported).

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
