Crate serial_enumerator 

serial_enumerator

A cross-platform serial port enumeration library for Linux, Windows, and macOS. Returns available serial ports with vendor, product, driver, and USB VID/PID information.

Unlike tools that blindly list every TTY device, this library validates each port and exposes a valid field so you can distinguish functional ports from false positives.

Quick Start

use serial_enumerator::get_serial_list;

for port in get_serial_list() {
    println!("{}  valid={}", port.name, port.valid);
}

CLI Tool

A command-line tool lser is included. Install with:

cargo install serial_enumerator
lser

Example Output

Linux:

SerialInfo { name: "/dev/ttyS0", valid: true, vendor: Some("pnp"), product: Some("PNP0501"), driver: Some("serial"), usb_info: None }
SerialInfo { name: "/dev/ttyUSB0", valid: true, vendor: Some("FTDI"), product: Some("Dual RS232-HS:00"), driver: Some("usbserial"), usb_info: Some(UsbInfo { vid: "0403", pid: "6010" }) }

Windows:

SerialInfo { name: "COM4", valid: true, vendor: Some("wch.cn"), product: Some("USB-SERIAL CH340"), driver: None, usb_info: Some(UsbInfo { vid: "1A86", pid: "7523" }) }
