Struct rustc_mir_build::thir::pattern::const_to_pat::fallback_to_const_ref::FallbackToConstRef
source · [−]pub(super) struct FallbackToConstRef(());Expand description
This error type signals that we encountered a non-struct-eq situation behind a reference.
We bubble this up in order to get back to the reference destructuring and make that emit
a const pattern instead of a deref pattern. This allows us to simply call PartialEq::eq
on such patterns (since that function takes a reference) and not have to jump through any
hoops to get a reference to the value.
