Implementations

impl TyFingerprint

pub fn for_inherent_impl(ty: &Ty) -> Option<TyFingerprint>

Creates a TyFingerprint for looking up an inherent impl. Only certain types can have inherent impls: if we have some struct S, we can have an impl S, but not impl &S. Hence, this will return None for reference types and such.

pub fn for_trait_impl(ty: &Ty) -> Option<TyFingerprint>

Creates a TyFingerprint for looking up a trait impl.

Trait Implementations

impl Clone for TyFingerprint

fn clone(&self) -> TyFingerprint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TyFingerprint

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

Formats the value using the given formatter.

impl Hash for TyFingerprint

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 TyFingerprint

fn eq(&self, other: &TyFingerprint) -> 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.
