This crate provides an API similar to std::process to create
and handle processes on Windows using the Win32 API (see this example).
Its main difference with std::process::Command is that it allows running
a command string instead of having to pass the command executable and the
arguments separately.
This is equivalent of running:
std::process::Command::new("cmd.exe").arg("/c").arg("any_command_string").spawn().expect("cannot spawn command");The only difference will be that the Child instance will use the PID of
the command instead of the PID of cmd.exe. This is important because
calling .kill() in the code above does not work as it kills the PID
of cmd.exe instead of the actual command that has been ran.
Add the following to your Cargo.toml:
[dependencies]
CreateProcessW = "0.1.0"This crate doesn't follow Rust's naming recommendations. If you want to stay consistent with other imported crates, use the following:
[dependencies]
create_process_w = { version = "0.1.0", package = "CreateProcessW" }The Command struct is used to configure and spawn processes:
useCreateProcessW::Command;let command = Command::new("cargo.exe clippy -- -D warnings").inherit_handles(true).current_dir(r"C:\Users\<user>\repos\<repo_name>");The spawn function spawns the process and returns a
Child that represents the spawned child process.
useCreateProcessW::Command;let child = Command::new("notepad.exe").spawn().expect("notepad failed to start");
std::thread::sleep(std::time::Duration::from_secs(2));
child.kill().expect("cannot kill process");let status = child.wait().expect("cannot wait process");if status.success(){println!("Success!");}else{println!("Process exited with status {}", status.code());}The status function spawns a child process, waits for
it to finish and returns its ExitStatus.
useCreateProcessW::Command;let status = Command::new("notepad.exe").status().expect("notepad failed to start");if status.success(){println!("Success!")}else{println!("Process exited with status {}", status.code())}
