Struct Logger

pub struct Logger { /* private fields */ }

Configuration and state for logging USB device events.

The logger handles output formatting and can write to both console and log files simultaneously.

Implementations

impl Logger

pub fn new( output_json: bool, log_file_path: Option<&str>, colorful: bool, ) -> Result<Self, Box<dyn Error>>

Creates a new logger instance.

Arguments

• output_json - Whether to format output as JSON
• log_file_path - Optional path to a log file
• colorful - Whether to use coloured output (ignored for JSON mode)

Errors

Returns an error if the log file cannot be created or opened.

Examples

use usbwatch_rs::logger::Logger;

// Console-only logger with plain text and colours
let logger = Logger::new(false, None, true)?;

// JSON logger with file output
let logger = Logger::new(true, Some("usb-events.json"), true)?;

pub fn log_device_event( &mut self, device_info: &UsbDeviceInfo, ) -> Result<(), Box<dyn Error>>

Logs a USB device event to console and file (if configured).

The output format depends on the output_json setting configured during logger creation.

Arguments

• device_info - Information about the USB device event

Errors

Returns an error if JSON serialisation fails or file writing fails.
