A slice represents a part of a string -\n * anything from the entire string to a single character, or even no\n * characters at all (a 0-length slice). Since a slice only has to specify\n * an offset and a length, copying and manipulating slices is a lot less\n * expensive than copying and manipulating the strings they reference.\n *\n * To further reduce gas costs, most functions on slice that need to return\n * a slice modify the original one instead of allocating a new one; for\n * instance, `s.split(\".\")` will return the text up to the first '.',\n * modifying s to only contain the remainder of the string after the '.'.\n * In situations where you do not want to modify the original slice, you\n * can make a copy first with `.copy()`, for example:\n * `s.copy().split(\".\")`. Try and avoid using this idiom in loops; since\n * Solidity has no memory management, it will result in allocating many\n * short-lived slices that are later discarded.\n *\n * Functions that return two slices come in two versions: a non-allocating\n * version that takes the second slice as an argument, modifying it in\n * place, and an allocating version that allocates and returns the second\n * slice; see `nextRune` for example.\n *\n * Functions that have to copy string data will return strings rather than\n * slices; these can be cast back to slices for further processing if\n * required.\n *\n * For convenience, some functions are provided with non-modifying\n * variants that create a new slice and return both; for instance,\n * `s.splitNew('.')` leaves s unmodified, and returns two values\n * corresponding to the left and right parts of the string.\n */\n\npragma solidity ^0.4.14;\n\nlibrary strings {\n struct slice {\n uint _len;\n uint _ptr;\n }\n\n function memcpy(uint dest, uint src, uint len) private pure {\n // Copy word-length chunks while possible\n for(; len >= 32; len -= 32) {\n assembly {\n mstore(dest, mload(src))\n }\n dest += 32;\n src += 32;\n }\n\n // Copy remaining bytes\n uint mask = 256 ** (32 - len) - 1;\n assembly {\n let srcpart := and(mload(src), not(mask))\n let destpart := and(mload(dest), mask)\n mstore(dest, or(destpart, srcpart))\n }\n }\n\n /*\n * @dev Returns a slice containing the entire string.\n * @param self The string to make a slice from.\n * @return A newly allocated slice containing the entire string.\n */\n function toSlice(string memory self) internal pure returns (slice memory) {\n uint ptr;\n assembly {\n ptr := add(self, 0x20)\n }\n return slice(bytes(self).length, ptr);\n }\n\n /*\n * @dev Returns the length of a null-terminated bytes32 string.\n * @param self The value to find the length of.\n * @return The length of the string, from 0 to 32.\n */\n function len(bytes32 self) internal pure returns (uint) {\n uint ret;\n if (self == 0)\n return 0;\n if (self & 0xffffffffffffffffffffffffffffffff == 0) {\n ret += 16;\n self = bytes32(uint(self) / 0x100000000000000000000000000000000);\n }\n if (self & 0xffffffffffffffff == 0) {\n ret += 8;\n self = bytes32(uint(self) / 0x10000000000000000);\n }\n if (self & 0xffffffff == 0) {\n ret += 4;\n self = bytes32(uint(self) / 0x100000000);\n }\n if (self & 0xffff == 0) {\n ret += 2;\n self = bytes32(uint(self) / 0x10000);\n }\n if (self & 0xff == 0) {\n ret += 1;\n }\n return 32 - ret;\n }\n\n /*\n * @dev Returns a slice containing the entire bytes32, interpreted as a\n * null-terminated utf-8 string.\n * @param self The bytes32 value to convert to a slice.\n * @return A new slice containing the value of the input argument up to the\n * first null.\n */\n function toSliceB32(bytes32 self) internal pure returns (slice memory ret) {\n // Allocate space for `self` in memory, copy it there, and point ret at it\n assembly {\n let ptr := mload(0x40)\n mstore(0x40, add(ptr, 0x20))\n mstore(ptr, self)\n mstore(add(ret, 0x20), ptr)\n }\n ret._len = len(self);\n }\n\n /*\n * @dev Returns a new slice containing the same data as the current slice.\n * @param self The slice to copy.\n * @return A new slice containing the same data as `self`.\n */\n function copy(slice memory self) internal pure returns (slice memory) {\n return slice(self._len, self._ptr);\n }\n\n /*\n * @dev Copies a slice to a new string.\n * @param self The slice to copy.\n * @return A newly allocated string containing the slice's text.\n */\n function toString(slice memory self) internal pure returns (string memory) {\n string memory ret = new string(self._len);\n uint retptr;\n assembly { retptr := add(ret, 32) }\n\n memcpy(retptr, self._ptr, self._len);\n return ret;\n }\n\n /*\n * @dev Returns the length in runes of the slice.
