Bit sets currently use 32bit words, this is not optimal since CPUs use 64-bit words and 64bit cache lines.

The core raptor algorithm still has ~10 allocations, ~200kb per instantiation, related to the use of BitSets. A static bitset might be faster, backed by a Vector{Int64}, so that there was no resizing …

Inspecting the dependency tree of `naga`, both `bitset` and `fixedbitset` (a dependency of `petgraph`) are both present, and do very similar things. `bitvec`, and `bitset`, by proxy are pretty large c…

### 概述
JAVA中BitSet就是“位图”数据结构，根据“位图”的语义，数据的存在性可以使用bit位上的1或0来表示；一个bit具有2个值：0和1，正好可以用来表示false和true, 对于数据的判重，通常使用HashMap来存储，不过hashmap需要消耗较多的内存，在大数据场景中不太适合；
### BitSet原理
JAVA中，一个long型数字占用64位空间，根…
