Scott and Stephen are back with another entry in the Deep .NET series, this time looking deep at System.Span enabling the representation of contiguous regions of arbitrary memory, regardless of whether that memory is associated with a managed object, is provided by native code via interop, or is on the stack. And it does so while still providing safe access with performance characteristics like that of arrays. Let's go deep on Span.

If stephen does a workshop of stuff like this in NDC London next year, I'll drop $2000 to attend like when Dave and Damiean did the early workshops on .net core in circa 2017.

This is freaking awesome!!! Right from the source, you should build a comprehensive "deep C# course" with all of this, for people that would like to purse perf related topics. Right now, I don't think there's a place where you can do that. It's basically spread around books, courses, blogs, etc etc. Really nice this one.

At 38:48 Toub is talking about how if you have a readonly span it will put it in the data block of the binary. Do things like ImmutableArray get the same benefit or is the JIT compiler extra aware of ReadOnlySpan to do that optimization?

My biggest question was how, using span, was the compiler able to keep such a tight loop when enumerating? Also could have mentioned that span does not allocate any memory or copy stuff around! This was a good one Scott/stephen! Thankyou
@davidantolingonzalez4929
@davidantolingonzalez4929 13 күн бұрын
It does allocate memory for the Span (two fields), but it does on the stack, not on the heap. Also, since it only stores an address of memory and an int, no copy of data is needed. The tight loop is achieved because T reference is basically a pointer so for enumerating the only thing it has to do is add "one" to the pointer times length, exactly the same as an array.

It's kinda freaking me out honestly that Scott doesn't know arrays in C# are always contiguous. I know he's a very good developer. Just surprised I guess. Arrays have to be contiguous or couldn't effectively rely on locality of references. That's the big reason why std::vector is now recommended as the primary algorithm in C++, instead of things like linked-lists, etc., because in modern architecture, it's actually faster to work with contiguous arrays for a lot of things that previously used to be not be option -- all because of modern hardware.
