Implementations

impl<'tcx> ExportedSymbol<'tcx>

pub fn symbol_name_for_local_instance( &self, tcx: TyCtxt<'tcx>, ) -> SymbolName<'tcx>

This is the symbol name of an instance if it is instantiated in the local crate.

Trait Implementations

impl<'tcx> Clone for ExportedSymbol<'tcx>

fn clone(&self) -> ExportedSymbol<'tcx>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for ExportedSymbol<'tcx>

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

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<__D> for ExportedSymbol<'tcx>

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

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

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

impl<'tcx> EraseType for ExportedSymbol<'tcx>

type Result = [u8; 24]

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for ExportedSymbol<'tcx>

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

impl ParameterizedOverTcx for ExportedSymbol<'static>

type Value<'tcx> = ExportedSymbol<'tcx>

impl<'tcx> PartialEq for ExportedSymbol<'tcx>

fn eq(&self, other: &ExportedSymbol<'tcx>) -> bool

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

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

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

impl<'tcx> Copy for ExportedSymbol<'tcx>

impl<'tcx> Eq for ExportedSymbol<'tcx>

impl<'tcx> StructuralPartialEq for ExportedSymbol<'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.
