pub struct HashingControls {
pub hash_spans: bool,
}
Expand description
Controls what data we do or do not hash.
Whenever a HashStable
implementation caches its
result, it needs to include HashingControls
as part
of the key, to ensure that it does not produce an incorrect
result (for example, using a Fingerprint
produced while
hashing Span
s when a Fingerprint
without Span
s is
being requested)

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