第三届中国Rust开发者大会 Candid: the interface description language of the Internet Computer smart contracts Yan Chen DFINITY Foundation Rust China Conf 2023 −− How DFINITY uses procedure macro to extend Rust the compiler. • Running example: Candid, a strongly typed serialization library • Extended language features: • Backward compatible API upgrades with subtyping • Type reflection • Structural typing Motivation as () Decode as (record { name : text }) Candid: a strongly typed interface description language • Primitive types • nat, int, nat{8-64}, int{8-64}, float{32,64}, bool, text • Composite types

and it can compile code from various programming languages, including Kotlin. Kotlin/Wasm is a new compilation target for Kotlin. You can use it in your Kotlin Multiplatform projects. With Kotlin/Wasm If you face any issues, please report them on GitHub. Compose Multiplatform for Web is based on new Kotlin/Wasm target. You can create a Kotlin Multiplatform project and experiment with sharing your Kotlin's static typing with the dynamic nature of data by utilizing both the full power of the Kotlin language and the opportunities provided by intermittent code execution in Jupyter notebooks and REPLs.

are intended to be brief notes, and you should be able to find more information in either the New Features document, or in the src/CHANGES file. This document describes only the changes from 2.0 to 2 version 1.3, you should also consult the 1.3 to 2.0 upgrading document. See also Overview of new features in Apache 2.2 Compile Time Configuration Changes The compilation process is very similar to then you will need to account for the module name changes mentioned above. If you choose to use the new default configuration file for version 2.2, you will find that it has been greatly simplified by removing
