RandomAccessRange: Infinite
Learn to implement and use infinite RandomAccessRanges in D programming by understanding how constant-time access with the opIndex() function enables efficient element retrieval. This lesson covers defining infinite ranges like SquaresRange, distinguishing between infinite and finite ranges, and applying these concepts to improve data manipulation.
We'll cover the following...
RandomAccessRange
RandomAccessRange represents ranges that allow accessing elements by the [] operator. As we covered in the operator overloading chapter, [] operator is defined by the opIndex() member function.
Importing the std.array module makes slices become RandomAccessRange ranges only if possible. For example, since UTF-8 and UTF-16 encodings do not allow accessing Unicode characters by an index, char and wchar arrays cannot be used as RandomAccessRange ranges of Unicode characters. On the other hand, since the codes of the UTF-32 encoding correspond ...
