Expand description

Reasons a method might not be object-safe.

Variants

StaticMethod(Option<(&'static str, Span)>, Span, bool)

e.g., fn foo()

ReferencesSelfInput(usize)

e.g., fn foo(&self, x: Self)

ReferencesSelfOutput

e.g., fn foo(&self) -> Self

WhereClauseReferencesSelf

e.g., fn foo(&self) where Self: Clone

Generic

e.g., fn foo<A>()

UndispatchableReceiver

the method’s receiver (self argument) can’t be dispatched on

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
