#[cfg(not(windows))]
fn main() {
println!("Not implemented");
}
</lang>
add this to the build.rs:
<lang rust>
fn main() {
#[cfg(windows)]
{
windows::build!(Windows::Win32::SystemServices::{GetCurrentProcess, ReportEventA, OpenEventLogA, ReportEvent_wType, HANDLE, PSTR},
Windows::Win32::Security::{OpenProcessToken, GetTokenInformation, TOKEN_ACCESS_MASK, TOKEN_INFORMATION_CLASS, TOKEN_USER, PSID});
}
}
</lang>
And this to cargo.toml:
<lang rust>
[target.'cfg(windows)'.dependencies]
windows = "0.7.0"
[target.'cfg(windows)'.build-dependencies]
windows = "0.7.0"
</lang>
