Variants§
Misc
Some built-in impl we don’t need to differentiate. This should be used unless more specific information is necessary.
Object(usize)
A built-in impl for trait objects. The index is only used in winnowing.
TraitUpcasting
A built-in implementation of Upcast
for trait objects to other trait objects.
This can be removed when feature(dyn_upcasting)
is stabilized, since we only
use it to detect when upcasting traits in hir typeck.
TupleUnsizing
Unsizing a tuple like (A, B, ..., X)
to (A, B, ..., Y)
if X
unsizes to Y
.
This can be removed when feature(tuple_unsizing)
is stabilized, since we only
use it to detect when unsizing tuples in hir typeck.
