exit program rust
To exit a Rust program, you can use the std::process::exit
function. This function immediately terminates the current process and returns the specified exit code.
Here is an example of how you can use std::process::exit
in Rust:
use std::process;
fn main() {
// Perform some operations
// Exit the program with exit code 0
process::exit(0);
}
In the code snippet above, the main
function performs some operations, and then the program exits using process::exit(0)
. The exit code 0 indicates a successful termination of the program. You can choose a different exit code as needed.
Keep in mind that when you call std::process::exit
, the program terminates immediately without executing any further code, including cleanup code or destructors. So, use it carefully and make sure you have handled any necessary cleanup before calling exit
.
