I see. Main difference I see is SA is a homogeneous container, which might be more contiguous/better for cache
straight-shoota: I'm pretty new, just experimenting mostly. But right now I have Vector (math) types in 2-4 dimensions, and currently using separate float ivars. Would like to back their storage in some container, so the method logic can map over them and reduce code by being generic for all 3 types.
Most operations are element-wise, so could reduce quite a bit of code by iterating over a generic container of some size to produce results for a given operation/vector type.
THat is the idea anyway. Not sure where to start yet :)
So how does that work? Is it an abstract type where I have to implement some methods?
2 methods*
1 that returns the size of your container, and another that gets the value at the given index
Thank you
makes it super easy to do like
arry.sort!
I am beginning to see how Crystal is very extensible with these mixin modules
It seems I have to study generic type parameters more because the compiler can't infer the type parameter and I'm not sure what to specify.
Heh, you're right. That is easy. I do have one complaint about the compiler here though.
When i
include Indexable(T), the compiler was smart enough to tell me I didn't implement unsafe_fetch. After I implemented that and tried using it, the compiler ended up overflowing the stack due to recursing infinitely. It wasn't until I implemented size that it worked. It makes me wonder why it just blew the stack instead of complaining that I didn't implement size.
got a small example of that behavior? I have a theory
<straight-shoota> and crystal-lang/crystal#9998
This ability to make anything indexable/iterable/whatever-able is fantastic.
Thank you for opening my blind eyes after reading the docs/api multiple times
It appears more has to be implemented, or what is the error here? https://play.crystal-lang.org/#/r/blfw
because there's no else in the case
speaking of, is there no way to view the
--error-trace on carc.in?
