Trait Implementations

impl<I> Clone for OpaqueTypeKey<I>

where I: Interner,

fn clone(&self) -> OpaqueTypeKey<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> Debug for OpaqueTypeKey<I>

where I: Interner,

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

Formats the value using the given formatter.

impl<I, __D> Decodable<__D> for OpaqueTypeKey<I>

where I: Interner, __D: Decoder, <I as Interner>::LocalDefId: Decodable<__D>, <I as Interner>::GenericArgs: Decodable<__D>,

fn decode(__decoder: &mut __D) -> OpaqueTypeKey<I>

impl<I, __E> Encodable<__E> for OpaqueTypeKey<I>

where I: Interner, __E: Encoder, <I as Interner>::LocalDefId: Encodable<__E>, <I as Interner>::GenericArgs: Encodable<__E>,

fn encode(&self, __encoder: &mut __E)

impl<I> Hash for OpaqueTypeKey<I>

where I: Interner,

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

where __H: Hasher,

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<I, __CTX> HashStable<__CTX> for OpaqueTypeKey<I>

where I: Interner, <I as Interner>::LocalDefId: HashStable<__CTX>, <I as Interner>::GenericArgs: HashStable<__CTX>,

fn hash_stable( &self, __hcx: &mut __CTX, __hasher: &mut StableHasher<SipHasher128>, )

impl<I> PartialEq for OpaqueTypeKey<I>

where I: Interner,

fn eq(&self, __other: &OpaqueTypeKey<I>) -> bool

Tests for self and other values to be equal, and is used by ==.

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