Generate did file automatically

Hi @peterparker,

We currently don’t have a clean way to auto generate candid for rust canister.

While there is a workaround as described in this post:

Automatic generation of Candid from Rust

Hey yeah we’ve been able to generate candid from rust for a while now. Not sure why it’s still kinda hidden from documentation. All the psychedelic projects use it ! You just need to add the CandidType derive, and the candid_service(query/update/init) macro to all the methods and types that need to be exported. Then, the export_service!() macro will generate function that returns the candid from rust, which can be run differently depending on the project setup For projects using a main.rs: You…

The SDK team envisions a redesign of Rust CDK which can provide more ergonomic developer experience. Auto generating candid is one of the features we plan to provide. The work is still in early stage.
