pub enum Reachability<T> {
Reachable(T),
Unreachable,
}
Expand description
Like Option<T>
but specifically for passing information about transitions
from reachable to unreachable state and the like from callees to callers.
Marked must_use
to force callers to update
FuncTranslationState::reachable
as necessary.
Variants§
Reachable(T)
The Wasm execution state is reachable, here is a T
.
Unreachable
The Wasm execution state has been determined to be statically
unreachable. It is the receiver of this value’s responsibility to update
FuncTranslationState::reachable
as necessary.
