Method data

base/string/string_piece.h:100–100

data() may return a pointer to a buffer with embedded NULs, and the returned buffer may or may not be null terminated. Therefore it is typically a mistake to pass data() to a routine that expects a NUL terminated string. Use "as_string().c_str()" if you really need to do this. Or better yet, change your routine so it does not rely on NUL termination.

    // this.  Or better yet, change your routine so it does not rely on NUL
    // termination.
    const char* data() const { return m_ptr; }
    size_t size() const { return m_length; }
    size_t length() const { return m_length; }
    bool empty() const { return m_length == 0; }
