This week we continue with iterators to get the functionality of
IEnumerable without the nasty garbage creation. This week the little iterator library gets support for sorting and binary searching. Read on for the details!

Back from a brief break, we pick up this week by finishing up the “modifying sequence operations” with some gems like
RandomShuffle and go through the “partitions” category with functions like
IsPartitioned. These are all solid algorithms with a lot of potential uses, so read on to see how to use them with iterators and for the source code that implements them!
Last week’s article introduced the concept of iterators as an alternative to the GC-heavy
IEnumerable. Today’s article expands the iterator library to include a bunch of more functions to make it useful. Think of these like the extension functions in
IndexOf, etc. These have all been tailored to iterators and none of them will create any garbage whatsoever.
In C#, just about everything is an
IEnumerable. Since LINQ syntax,
foreach loops, and the
System.Linq namespace are all designed to work with
IEnumerable, you’ve got lots of tools to use. Unfortunately, the core of
IEnumerable is the
GetEnumerator function which usually creates garbage and eventually causes memory fragmentation and GC framerate spikes. Do we simply stop using all of these nice tools? Normally the answer is “yes”, but today’s article shows you another way.
Last time we saw that calling a non-default constructor on a generic struct (
MyStruct<T>) causes garbage creation. That garbage creation is subtle, but can have big impacts on framerate and memory usage. Today we’ll see two more ways that structs can create garbage and hopefully avoid some pitfalls. Read on to find out how!
As Unity programmers, the garbage collector is sadly our enemy. C#
structs are often a great tool to avoid allocating objects that need to later be garbage-collected. This isn’t always the case though. Sometimes even a
struct can allocate garbage. Today’s article points out one of those ways so you won’t be fooled into thinking you’ve stopped the GC just because you’re using a
struct. Read on to learn more!
While little utilized, C#’s
struct type can come in really handy sometimes. Today’s article shows how to use it to get a lot more mileage out of modern CPUs’ caches to really boost your app’s performance. Read on for some quick tips!
C and C++ have a great feature call the “union”. It’s like a
struct except it only has one of the fields at a time. C# lacks this feature, but with some trickery it can be added in. Today’s article shows how to do that!
It’s easy to forget about
struct in C#. After all, it’s not available in other languages like Java or AS3 and it seems to have fewer features than good old
struct can really help you out when it comes to garbage creation! Today’s article discusses some strategies to get the most out of
struct. Read on to learn how to use structs to put a stop to that pesky garbage collector!
