Struct ra_ap_rustc_data_structures::stable_hasher::HashingControls

pub struct HashingControls {
    pub hash_spans: bool,
}

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 Spans when a Fingerprint without Spans is being requested)

Fields

hash_spans: bool

Trait Implementations

impl Clone for HashingControls

fn clone(&self) -> HashingControls

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HashingControls

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for HashingControls

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HashingControls

fn eq(&self, other: &HashingControls) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
