Statics§

bit: Get i-th bit from bytes slice. Index i starts from 0.
bits_to_bytes: Convert bits, Vec slice of bool into bytes, Vec<u8>.
bits_to_usize: Convert a Vec slice of bit or bool into a number as usize.
bytes_to_bits: Convert a bytes slice into a Vec of bit.
bytes_to_int: Convert big-endian bytes into base10 or decimal number.
bytes_to_slicebit: Convert (bytes slice + Range) representation into bits in forms of Vec<bool>.
cast: Cast from a typed scalar to another based on num_traits
get_sorted_indices: Get sorted indices from unsorted slice.
int_to_bytes: Get a compressed bytes (leading-zero-truncated big-endian bytes) from a u64.
len_lcp: Get length of the longest common prefix bits for the given two slices.
nbytes_across: Get the required length of bytes from a Range, bits indices across the bytes.
random_byte: Generate a random byte based on rand::random.
random_bytes: Generate random bytes of the given length.
random_hash: Generate a random Hash, byte-array of HASH_LEN length.
random_hashes: Generate a vector of random Hash with the given length.
shuffle: Shuffle a slice using Fisher-Yates algorithm.
slice_to_hash: Get a fixed length byte-array or Hash from slice.
