anyway, some 🦀 content today:

I'm considering using serde in rusticl, however my use case is not to parse arbitrary data, but always structs with no custom data allowed. In short: the struct defines the data layout.

And we have some helpers in mesa dealing with reading/writing data to a blob.

So I'm wondering if a custom serde serialize/deserializer is what I want, or if I want something more special/focused as serde seems to be too generic for my use case here.

@karolherbst if you don't need to be generic over different data types, writing your own derive macro might be the solution that produces the most efficient code ... /me hides

uhh, so a few days ago I found out, that passing structs by value in through OpenCL C or SPIR-V in fact doesn't pass the argument by value.

Turns out we don't handle the SPIR-V "ByVal" Function Parameter Attribute...

this might explain a few bugs I've seen in the past...

@karolherbst it's awesome to see rusticl improve so quickly. basically in real-time :) thank you for the work you do!

rustc 1.78 is great, it already found one bug in #rusticl :)

@karolherbst and there you were, having fun dereferencing unaligned pointers? 😄
