Enum rustc_middle::mir::UnwindTerminateReason

pub enum UnwindTerminateReason {
    Abi,
    InCleanup,
}

The reason we are terminating the process during unwinding.

Variants

Abi

Unwinding is just not possible given the ABI of this function.

InCleanup

We were already cleaning up for an ongoing unwind, and a second, nested unwind was triggered by the drop glue.

Implementations

impl UnwindTerminateReason

pub fn as_str(self) -> &'static str

pub fn as_short_str(self) -> &'static str

A short representation of this used for MIR printing.

pub fn lang_item(self) -> LangItem

Trait Implementations

impl Clone for UnwindTerminateReason

fn clone(&self) -> UnwindTerminateReason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnwindTerminateReason

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

Formats the value using the given formatter.

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

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

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

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

impl Hash for UnwindTerminateReason

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<'__ctx> HashStable<StableHashingContext<'__ctx>> for UnwindTerminateReason

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

impl PartialEq<UnwindTerminateReason> for UnwindTerminateReason

fn eq(&self, other: &UnwindTerminateReason) -> 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> TypeFoldable<TyCtxt<'tcx>> for UnwindTerminateReason

fn try_fold_with<__F: FallibleTypeFolder<TyCtxt<'tcx>>>( self, __folder: &mut __F ) -> Result<Self, __F::Error>

The entry point for folding. To fold a value t with a folder f call: t.try_fold_with(f).

fn fold_with<F>(self, folder: &mut F) -> Selfwhere F: TypeFolder<I>,

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

impl<'tcx> TypeVisitable<TyCtxt<'tcx>> for UnwindTerminateReason

fn visit_with<__V: TypeVisitor<TyCtxt<'tcx>>>( &self, __visitor: &mut __V ) -> ControlFlow<__V::BreakTy>

The entry point for visiting. To visit a value t with a visitor v call: t.visit_with(v).

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.
