Type Alias rustc_middle::query::queries::symbol_name::ProvidedValue

pub type ProvidedValue<'tcx> = SymbolName<'tcx>;

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> {
    pub name: &'tcx str,
}

Fields

name: &'tcx str

&str gives a consistent ordering, which ensures reproducible builds.

Implementations

impl<'tcx> SymbolName<'tcx>

fn decode(decoder: &mut D) -> Self

impl<'tcx> Display for SymbolName<'tcx>

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

Formats the value using the given formatter.

impl<'tcx, __E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<__E> for SymbolName<'tcx>

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

impl<'tcx> EraseType for SymbolName<'tcx>

type Result = [u8; 16]

impl<'tcx> Hash for SymbolName<'tcx>

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<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for SymbolName<'tcx>

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

impl<'tcx> Ord for SymbolName<'tcx>

fn cmp(&self, other: &SymbolName<'tcx>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'tcx> PartialEq<SymbolName<'tcx>> for SymbolName<'tcx>

fn eq(&self, other: &SymbolName<'tcx>) -> 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.

impl<'tcx> PartialOrd<SymbolName<'tcx>> for SymbolName<'tcx>

fn partial_cmp(&self, other: &SymbolName<'tcx>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'tcx> Value<TyCtxt<'tcx>> for SymbolName<'_>

fn from_cycle_error( tcx: TyCtxt<'tcx>, _: &[QueryInfo], _guar: ErrorGuaranteed ) -> Self

impl<'tcx> Copy for SymbolName<'tcx>

impl<'tcx> Eq for SymbolName<'tcx>

impl<'tcx> StructuralPartialEq for SymbolName<'tcx>

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.
