0.8.1 depends on a version of generic_array that has an unsoundness bug.
The VarBlake2b hasher now gives us a Box<[u8]> instead of a Vec, which meant it could no longer be passed straight to Identity::truncate in ratman-identity. I noticed that that method took an Into<&Vec<u8>>, which I don't think anything other than Vec actually implements -- other things implement Into<Vec<u8>>, but not Into<&Vec<u8>>. I think the correct type to use here to allow a vec to be borrowed is AsRef<[u8]> (which types like Box<[u8]> do actually implement), so I've changed it to take that instead. --- Cargo.lock | 94 +++++---------------------- irdest-core/Cargo.toml | 2 +- irdest-core/src/auth/pwhash.rs | 4 +- irdest-core/src/messages/generator.rs | 2 +- ratman/identity/Cargo.toml | 2 +- ratman/identity/src/lib.rs | 15 +++-- 6 files changed, 31 insertions(+), 88 deletions(-)
