How do I set the Windows execution level to ask user for administrator privileges for a Rust program?

Question

I'm writing a Windows CLI app and I need to run it as administrator. In C# I would add this line to app.manifest:

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" /> 

How I do that in Rust?

Too late, but answering anyway. :-)

Please take a look at the winres library. It contains the following example:

The following manifest will brand the exe as requesting administrator privileges. Thus, everytime it is executed, a Windows UAC dialog will appear.

let mut res = winres::WindowsResource::new();
res.set_manifest(r#"
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
        <requestedPrivileges>
            <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
        </requestedPrivileges>
    </security>
</trustInfo>
</assembly>
"#);

The full example is documented and available here.

I have been using this library in a project that contains an icon and requires admin privileges, its build.rs using winres is hosted here. See the generated executable:
