Expand description
Reasons a method might not be object-safe.
Variants§
StaticMethod(Option<((String, Span), (String, Span))>)
e.g., fn foo()
ReferencesSelfInput(Option<Span>)
e.g., fn foo(&self, x: Self)
ReferencesSelfOutput
e.g., fn foo(&self) -> Self
ReferencesImplTraitInTrait(Span)
e.g., fn foo(&self) -> impl Sized
AsyncFn
e.g., async fn foo(&self)
WhereClauseReferencesSelf
e.g., fn foo(&self) where Self: Clone
Generic
e.g., fn foo<A>()
UndispatchableReceiver(Option<Span>)
the method’s receiver (self
argument) can’t be dispatched on

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
