typeshare VS swift

It doesn’t generate a complete client but 1Password’s Typeshare can generate TypeScript from Rust data structures https://github.com/1password/typeshare

Aren't there things like typeshare to aid with that case?

Sure. I would love some help. I am visiting my family all March (I am typing this from the airport), so I don't know how much time I'll have to work on trane for the next month. But maybe that gives you some time to use it, and read the code and docs.

I am not going to put my personal email here, and I don't see an option to send private messages on hn, although it's probably out there somewhere. Probably in the commits, lol. Worst case, feel free to open an issue on the trane repo.

As a first ask, what do you think of this: https://github.com/1Password/typeshare?

I figured writing the UI in rust is probably not a good idea. The ecosystem for UI is very immature and the language itself is probably overkill. But doing it in typescript/html/css requires you to understand the internal data structures (all the JSON files you see in the courses are just serialized rust objects).

I found that repo and it seems like a promising approach to autogenerate the types and make the interaction easier.

How does this compare to typeshare?

Recently, 1Password open-sourced Typeshare, to help Rust developers create FFI (foreign function interfaces). Curious to learn more? Join the team behind the tool this week on Zoom at 11a Eastern to discuss Typeshare and answer any questions.

Newly open-sourced project that might be handy for some of you all https://github.com/1Password/typeshare

Typeshare by 1Password, the original inspiration for this blog post. It's available on crates.io.

For sure! We actually open sourced an early version of it a while back (https://github.com/1Password/typeshare), but it became a slowdown to work on it both for our own internal needs and for the outside world, so that was abandoned and it's since fallen out of sync with the project internally today.

This algorithm produces biased result with probability 1/2^(32-bitwidth(N)). Using 64 or 128 random bits can make the bias practically undetectable. Comprehensive overview of the approach can be found here: https://github.com/apple/swift/pull/39143

Because of C/C++ interop, and integration with CMake, you can just add Swift to a Zephyr project and it pretty much Just Works. [The docs](https://github.com/apple/swift/blob/main/docs/EmbeddedSwift/...) should mostly apply to the Zephyr SDK as well.

Fortunately, the Observation framework is part of the Swift 5.9 standard library. We can learn more information by examining its source code.

They do! See https://github.com/apple/swift/blob/main/docs/LibraryEvoluti...

You can also see an example of what a different high level language integration with Swift ABI looks like here: https://github.com/dotnet/designs/blob/main/proposed/swift-i...

So is differentiable Swift a package for Swift or is it part of the Swift standard library? The video says go to swift.org but I can't find any info about differentiable Swift on that site.

Swift's Differentiable Programming Manifesto. Swift has a powerful differentiable programming component, integrated with the compiler.

You can do the same thing the other way around - https://github.com/apple/swift/blob/main/docs/Android.md.

Codable (along with other derived conformances like Equatable, Hashable, and RawRepresentable) is indeed built in to the compiler[0], but unlike Serde, it operates during type-checking on a fully-constructed AST (with access to type information), manipulating the AST to insert code. Because it operates at a later stage of compilation and at a much higher level (with access to type information), the work necessary is significantly less.

With ongoing work for Swift macros, it may eventually be possible to rip this code out of the compiler and rewrite it as a macro, though it would need to be a semantic macro[1] rather a syntactic one, which isn't currently possible in Swift[2].

`Int` is a regular struct with a single stored property of type `Builtin.Word` . But the latter is a magical compiler built-in. Source for integer types is generated from this template - https://github.com/apple/swift/blob/9da65ca0a15fdf341649c994b0a77ec3b71f2687/stdlib/public/core/IntegerTypes.swift.gyb
