A Vob is a "vector of bits": a sequence of bits which exposes a Vec-like
interface. Whereas Vec<bool> requires 1 byte of storage per bit, Vob
requires only 1 bit of storage per bit. For larger numbers of bits, Vobs can
lead to a significant memory decrease and performance increase. Vob is broadly
similar to BitVec, but has an API more
closely aligned to Vec<bool> and allows non-32-bit backing storage. On 64-bit
systems this can lead to a substantial performance increase.
Vob currently doesn't implement all of the same functions one would find in
Vec<bool>. We welcome contributions!
