Fancy Log

A simple and customizable logging library for Rust, providing colored console output with timestamped log messages and configurable log levels.

Features

• Log Levels: Supports Error, Warn, Info, and Debug log levels.
• Colored Output: Logs are displayed in different colors based on the log level (e.g., red for errors, yellow for warnings).
• Timestamps: Each log message includes a timestamp in HH:MM:SS format.
• Thread-Safe: Uses a global, thread-safe log level configuration.
• Customizable: Easily set the minimum log level to filter messages.

Installation

Add the following to your Cargo.toml:

[dependencies]
fancy-log = "0.1.0"

Usage

Basic Example

use fancy_log::{log, set_log_level, LogLevel};

fn main() {
    // Set the minimum log level to Info
    set_log_level(LogLevel::Info);

    // Log messages
    log(LogLevel::Info, "This is an info message");
    log(LogLevel::Warn, "This is a warning message");
    log(LogLevel::Error, "This is an error message");
    log(LogLevel::Debug, "This debug message will not be shown");
}

Setting Log Level

You can configure the log level to filter out messages below a certain threshold:

use fancy_log::{set_log_level, LogLevel};

// Set log level to Debug to show all messages
set_log_level(LogLevel::Debug);

Log Output

• Error: Printed to stderr in red.
• Warn: Printed to stderr in yellow.
• Info: Printed to stdout in white.
• Debug: Printed to stdout in blue.

Example output:

12:34:56 This is an info message
12:34:56 This is a warning message
12:34:56 This is an error message

Dependencies

• chrono = "0.4": For timestamp formatting.
• once_cell = "1.21": For thread-safe global log level storage.
• termcolor = "1.4.1": For colored console output.
• serde = { version = "1", features = ["derive"] }: For log level deserialization.
