This reverts the implementation of
SeekNum::from_block_byte
which was merged as part of #435.I'm not exactly sure what the issue is and it's somewhat difficult to debug in that it's code that involves both generics and macros causing an error as part of any failure in a long chain of checked arithmetic, which I'm trying to debug from the context of a concrete stream cipher impl (both
chacha20
andsalsa20
) where it's operating over a generic type.The error manifests as
OverflowError
:RustCrypto/stream-ciphers#205 (comment)
This commit reverts to the previous implementation, which is at least much simpler.
