[−][src]Struct rustc_mir_build::thir::pattern::const_to_pat::fallback_to_const_ref::FallbackToConstRef

pub(super) struct FallbackToConstRef(());

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.
