/* | |
* @title String & slice utility library for Solidity contracts. | |
* @author Nick Johnson <[email protected]> | |
* | |
* @dev Functionality in this library is largely implemented using an | |
* abstraction called a 'slice'. A slice represents a part of a string - | |
* anything from the entire string to a single character, or even no | |
* characters at all (a 0-length slice). Since a slice only has to specify | |
* an offset and a length, copying and manipulating slices is a lot less | |
* expensive than copying and manipulating the strings they reference. | |
* | |
* To further reduce gas costs, most functions on slice that need to return | |
* a slice modify the original one instead of allocating a new one; for | |
* instance, `s.split(".")` will return the text up to the first '.', | |
* modifying s to only contain the remainder of the string after the '.'. | |
* In situations where you do not want to modify the original slice, you | |
* can make a copy first with `.copy()`, for example: | |
* `s.copy().split(".")`. Try and avoid using this idiom in loops; since | |
* Solidity has no memory management, it will result in allocating many | |
* short-lived slices that are later discarded. | |
* | |
* Functions that return two slices come in two versions: a non-allocating | |
* version that takes the second slice as an argument, modifying it in | |
* place, and an allocating version that allocates and returns the second | |
* slice; see `nextRune` for example. | |
* | |
* Functions that have to copy string data will return strings rather than | |
* slices; these can be cast back to slices for further processing if | |
* required. | |
* | |
* For convenience, some functions are provided with non-modifying | |
* variants that create a new slice and return both; for instance, | |
* `s.splitNew('.')` leaves s unmodified, and returns two values | |
* corresponding to the left and right parts of the string. | |
