What are the key features of RustLogs (RLG)?



How do I add RustLogs (RLG) to my Rust project?

To add RustLogs (RLG) to your Rust project, simply add the following line to your Cargo.toml file:

rlg = "0.0.3"

How do I create a new log entry?

To create a new log entry using RustLogs (RLG), you can use the Log::new() function:

use rlg::log::Log;
use rlg::log_format::LogFormat;
use rlg::log_level::LogLevel;

let log_entry = Log::new(
    "This is a sample log message",

How do I log a message asynchronously?

To log a message asynchronously using RustLogs (RLG), you can use the log() method on a log entry:

tokio::runtime::Runtime::new().unwrap().block_on(async {

How can I customize the log file path?

By default, RustLogs (RLG) logs to a file named "RLG.log" in the current directory. You can customize the log file path by setting the LOG_FILE_PATH environment variable:

std::env::set_var("LOG_FILE_PATH", "/path/to/log/file.log");



What macros are available in RustLogs (RLG)?

RustLogs (RLG) provides several helpful macros to simplify common logging tasks:

How do I use the macro_log! macro?

The macro_log! macro allows you to create a new log entry easily. Here's how you can use it:

let log = macro_log!(session_id, time, level, component, description, format);

How do I use the macro_info_log! macro?

The macro_info_log! macro creates an info log with default session ID and format. Here's how you can use it:

let log = macro_info_log!(time, component, description);

How do I conditionally log a message based on a predicate?

You can use the macro_log_if! macro to conditionally log a message based on a predicate:

macro_log_if!(predicate, log);

If the predicate evaluates to true, the log message will be printed using macro_print_log!.


Error Handling

How does RustLogs (RLG) handle errors during logging operations?

Errors can occur during logging operations, such as file I/O errors or formatting errors. The log() method returns a Result<(), io::Error> that indicates the outcome of the logging operation. You should handle potential errors appropriately in your code:

match log_entry.log().await {
    Ok(_) => println!("Log entry successfully written"),
    Err(err) => eprintln!("Error logging entry: {}", err),
