Hi, I'm currently making a package from a rust library with ffi. I'd like to use a rust toolchain to compile it when installing it as a xmake package. I've manage to make a rust toolchain package that works when I test it manually, but for some reason when used as a custom toolchain in my library's package it cannot find rust's binaries. I've compared my toolchain with Zig's and muslcc and I cannot find any issues. I'm asking for some help please.

Here's my lirary's package

package("wgsl-validator")
    set_homepage("https://github.com/NazaraEngine/wgsl-validator")
    set_description("WGSL validator in Rust with C bindings.")
    set_license("MIT")

    add_urls("https://github.com/NazaraEngine/wgsl-validator.git")

    add_urls("https://github.com/NazaraEngine/wgsl-validator/archive/refs/tags/$(version).tar.gz",
             "https://github.com/NazaraEngine/wgsl-validator.git")

    on_install(function (package)
        io.writefile("xmake.lua", [[
            add_requires("rust")
            add_requires("cargo::naga latest", { configs = { features = "wgsl-in" } })

            target("wgsl-validator")
                set_kind("static")
                set_toolchains("rust@rust")
                add_files("src/lib.rs")
                add_headerfiles("ffi/*.h")
                set_values("rust.cratetype", "staticlib")
                add_packages("cargo::naga")
        ]])
        import("package.tools.xmake").install(package, configs)
    end)

    on_test(function (package)
        assert(package:check_csnippets({test = [[
            #include <wgsl_validator.h>
            #define WGSL_SOURCE(...) #__VA_ARGS__
            const char* wgsl_source = WGSL_SOURCE(
                @fragment
                fn main_fs() -> @location(0) vec4<f32> {
                    return vec4<f32>(1.0, 1.0, 1.0, 1.0);
                }
            );

            void test() {
                char* error;
                wgsl_validator_t* validator = wgsl_validator_create();
                if(wgsl_validator_validate(validator, wgsl_source, &error))
                    wgsl_validator_free_error(error);
                wgsl_validator_destroy(validator);
            }
        ]]}, { configs = { languages = "c17" } }))
    end)

Here's the rust toolchain package

package("rust")
    set_kind("toolchain")
    set_homepage("https://rust-lang.org")

    if is_host("windows") then
        add_urls("https://static.rust-lang.org/rustup/archive/$(version)/x86_64-pc-windows-msvc/rustup-init.exe")

        add_versions("1.28.1", "7b83039a1b9305b0c50f23b2e2f03319b8d7859b28106e49ba82c06d81289df6")
    end

    if is_host("linux") then
        add_extsources("apt::rustup")
        add_extsources("pacman::rustup")
    elseif is_host("macosx") then
        add_extsources("brew::rustup")
    end

    on_install("@macosx", "@linux", "@windows", "@msys", "@bsd", function (package)
        local cachedir = package:cachedir()
        local installdir = package:installdir()
        if is_host("windows") then
            os.execv(package:originfile(), { "--no-modify-path", "--profile", "minimal", "--quiet", "-y" }, { envs = { RUSTUP_HOME = path.join(cachedir, ".rustup"), CARGO_HOME = path.join(cachedir, ".cargo") } })
        else
            local outdata, _ = os.iorun("curl https://sh.rustup.rs -sSf")
            io.writefile(path.join(cachedir, "rustup-init.sh"), outdata)
            os.execv(os.shell(), { path.join(cachedir, "rustup-init.sh"), "--no-modify-path", "--profile", "minimal", "--quiet", "-y" }, { envs = { RUSTUP_HOME = path.join(cachedir, ".rustup"), CARGO_HOME= path.join(cachedir, ".cargo") } })
        end
        os.mv(path.join(cachedir, ".rustup", "toolchains", "*", "*"), installdir)
        package:addenv("PATH", installdir)
    end)

    on_test(function (package)
        os.vrun("cargo --version")
    end)

And here's what the output from the command xmake l scripts/test.lua --shallow -vD wgsl-validator looks like

{ 
  "wgsl-validator" 
}

It works, it's always the simplest things that make such bugs
