Enum rustc_middle::mir::CallSource

pub enum CallSource {
    OverloadedOperator,
    MatchCmp,
    Misc,
    Normal,
}

Represents how a TerminatorKind::Call was constructed, used for diagnostics

Variants

OverloadedOperator

This came from something such as a > b or a + b. In THIR, if from_hir_call is false then this is the desugaring.

MatchCmp

This was from comparison generated by a match, used by const-eval for better errors when the comparison cannot be done in compile time.

(see https://github.com/rust-lang/rust/issues/90237)

Misc

Other types of desugaring that did not come from the HIR, but we don’t care about for diagnostics (yet).

Normal

Normal function call, no special source

Implementations

impl CallSource

pub fn from_hir_call(self) -> bool

Trait Implementations

impl Clone for CallSource

fn clone(&self) -> CallSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CallSource

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

Formats the value using the given formatter.

impl<__D: TyDecoder> Decodable<__D> for CallSource

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

impl<__E: TyEncoder> Encodable<__E> for CallSource

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

impl Hash for CallSource

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 CallSource

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

impl PartialEq for CallSource

fn eq(&self, other: &CallSource) -> 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 CallSource

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) -> Self

where 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 CallSource

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

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

impl Copy for CallSource

impl StructuralPartialEq for CallSource

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.
