A crate aims to resolve small bits values storage and operations problem.
Small bits values will be stored in a vector of Block - which is a PrimInt in
memory. Here, we only consider the case that one Block will store some of the
small bits values, such as 1, 2, 3, 4, 5 bits stored in u8, u16, u32, u64.
WARN: In this crate, I(@zitsen) decided to use
RawVec from unstable alloc crate as vector background,
which means the API would only be avaliable in nightly version of Rust and that
the API might be changed in some time the alloc API changed.
So a stable version may never give out.
See usage in struct documentation.
