Aaron Turon 912a9675c0 Make from_bits in bitflags! safe; add from_bits_truncate ... Previously, the `from_bits` function in the `std::bitflags::bitflags` macro was marked as unsafe, as it did not check that the bits being converted actually corresponded to flags. This patch changes the function to check against the full set of possible flags and return an `Option` which is `None` if a non-flag bit is set. It also adds a `from_bits_truncate` function which simply zeros any bits not corresponding to a flag. This addresses the concern raised in https://github.com/mozilla/rust/pull/13897		2014-05-15 13:50:33 -07:00
