Structured Persistent Logger

structured_persistent_logger is a Rust crate providing a structured logging solution that is compatible with the standard log crate. It features persistent logging capabilities, allowing for the retention and structured formatting of log records.

Features

• Integration with the standard log crate.
• Structured logging with JSON formatting.
• Persistent logging capabilities across application lifecycle.
• Thread-safe logging with support for multi-threaded environments.

Installation

Add structured_persistent_logger to your Cargo.toml:

[dependencies]
structured_persistent_logger = "0.1.0"
log = "0.4.0"

Usage

To use structured_persistent_logger, initialize it at the start of your application:

use structured_persistent_logger::StructuredPersistentLogger;

fn main() {
    StructuredPersistentLogger::init();
    add_persistent_logs! {
        "key1" => json!("value1"),
        "key2" => json!({"nested": "structure"})
    };
    log::info!("This is an info message");
    // output:
    // {
    //    "key1": "value1",
    //    "key2": { "nested": "structure" },
    //    "message": "This is an info message",
    //    "level": "INFO"
    // }
}

Adding Persistent Logs

You can add persistent logs that will be included in every log message:

use structured_persistent_logger::add_persistent_logs;
use serde_json::json;

fn some_function() {
    add_persistent_logs! {
        "key1" => json!("value1"),
        "key2" => json!(123)
    };
}

Configuration

The logger can be configured to adjust its behavior, such as setting log levels or customizing the format of log entries.
