Overlong impl

[nrc]

impl<BorrowType, K, V, NodeType, HandleType> Handle<NodeRef<BorrowType, K, V, NodeType>, HandleType> {

I assume this is an off by n error.

[nrc]

This isn't a dup of #1037 - that is poor formatting where we split the type rather than the impl, here we are not splitting at all and cause an overflow.

See #1049 (comment) for hints about how to fix.
