# Least-Significant-First Bit Traversal This type orders the bits in an element with the least significant bit first and the most significant bit last, in contiguous order across the element. The guide has [a chapter][0] with more detailed information on the memory representation this produces. This is the default type parameter used throughout the crate. If you do not have a desired memory representation, you should continue to use it, as it provides the best codegen for bit manipulation. [0]: https://bitvecto-rs.github.io/bitvec/memory-representation
