Type Alias rustc_middle::query::queries::unused_generic_params::ProvidedValue

pub type ProvidedValue<'tcx> = UnusedGenericParams;

This type alias specifies the type returned from query providers and the type used for decoding. For regular queries this is the declared returned type V, but arena_cache will use <V as Deref>::Target instead.

Aliased Type

struct ProvidedValue<'tcx>(FiniteBitSet<u32>);

Fields

0: FiniteBitSet<u32>

Trait Implementations

impl Clone for UnusedGenericParams

fn clone(&self) -> UnusedGenericParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnusedGenericParams

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for UnusedGenericParams

fn decode(__decoder: &mut __D) -> Self

impl Default for UnusedGenericParams

fn default() -> Self

Returns the “default value” for a type.

impl<__E: Encoder> Encodable<__E> for UnusedGenericParams

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

impl EraseType for UnusedGenericParams

type Result = [u8; 4]

impl<'__ctx> HashStable<StableHashingContext<'__ctx>> for UnusedGenericParams

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher )

impl ParameterizedOverTcx for UnusedGenericParams

type Value<'tcx> = UnusedGenericParams

impl PartialEq<UnusedGenericParams> for UnusedGenericParams

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
