WebJul 6, 2013 · Preamble: Twos-Complement Numbers. All of these operators share something in common -- they are "bitwise" operators. That is, they operate on numbers (normally), but instead of treating that number as if it were a single value, they treat it as if it were a string of bits, written in twos-complement binary. A two's complement binary is … Webloop through the array, shifting bits: On the first byte (unreversed) I had 6 bits that I need to shift by in order to move the valid ones to the start ( 0b11000000 ), so I shift each byte by 6, store what I shift, and push it to the end of the next (reversed) byte.
WebRepresentation of a borrowed C string. This type represents a borrowed reference to a nul-terminated array of bytes. It can be constructed safely from a & [ u8] slice, or unsafely from a raw *const c_char. It can then be converted to a Rust & str by performing UTF-8 validation, or into an owned CString.
