bors b18b9edf00 Auto merge of #52681 - pnkfelix:z-borrowck-migrate, r=nikomatsakis ... Add `-Z borrowck=migrate` This adds `-Z borrowck=migrate`, which represents the way we want to migrate to NLL under Rust versions to come. It also hooks this new mode into `--edition 2018`, which means we're officially turning NLL on in the 2018 edition. The basic idea of `-Z borrowck=migrate` that there are cases where NLL is fixing old soundness bugs in the borrow-checker, but in order to avoid just breaking code by immediately rejecting the programs that hit those soundness bugs, we instead use the following strategy: If your code is accepted by NLL, then we accept it. If your code is rejected by both NLL and the old AST-borrowck, then we reject it. If your code is rejected by NLL but accepted by the old AST-borrowck, then we emit the new NLL errors as **warnings**. These warnings will be turned into hard errors in the future, and they say so in these diagnostics. Fix #46908		2018-07-27 09:10:07 +00:00
