Function process_list 

pub fn process_list(pattern: &str) -> Result<Vec<ProcessInfo>, ProcessError>

List processes matching a pattern (or all if pattern is empty).

Arguments

• pattern - The pattern to match against process names (empty string for all processes)

Returns

• Ok(Vec<ProcessInfo>) - A vector of process information for matching processes
• Err(ProcessError) - An error if the list operation failed

Examples

// List all processes
use sal_process::process_list;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let processes = process_list("")?;

    // List processes with "server" in their name
    let processes = process_list("server")?;
    for proc in processes {
        println!("PID: {}, Name: {}", proc.pid, proc.name);
    }
    Ok(())
}
