Including Rust files inside Swift project

[asdf]

Is it possible to include rust files in swift project?
Something like:

SwiftProj
    |---Package.swift
    |---Sources
          |---SwiftModule
          |---RustModule
               |---libheader.h
               |---Cargo.toml
               |---src
                    |---lib.rs

Then just invoke swift build

Today it is not possible to do this. In the eventual future it should be possible to run external build tools, but Rust is a complex one to express. I do not believe there is any roadmap to do this today.

If this goes through, I suspect something like what you are asking would become possible:

SE-0303: Package Manager Extensible Build Tools

The review of SE-0303, begins now and runs through March 12, 2021. Reviews are an important part of the Swift evolution process. All review feedback should be either on this forum thread or, if you would like to keep your feedback private, directly to the review manager or direct message in the Swift forums). What goes into a review of a proposal? The goal of the review process is to improve the proposal under review through constructive criticism and, eventually, determine the direction of S…

If you're interested in doing something like this today, and you're willing to put a lot of work into it, you can go down the path of using bazel which supports rust and Swift and they could theoretically intermingle in the same build that way (although I don't know of anyone doing this today for rust specifically)

would it be possible without other build tool?
i mean just invoke swift build and swiftPM will invoke cargo

[Keith (Keith Smiley)]

Nope, as others said rust isn't supported by swiftpm today.
