rich_err is a Rust library designed to simplify and enrich error handling by adding structured and meaningful context to errors. It provides a developer-friendly API for consistent and detailed error reporting, making debugging and error analysis more efficient.

Features

• Rich Error Context: Easily add and format detailed context to errors for improved debugging.
• Zero-Cost Abstractions: Designed with performance in mind, adding context without unnecessary overhead.
• Easy to Use: Simple and intuitive API for managing error contexts.

Getting Started

To include rich_err in your project, add the following line to your Cargo.toml:

[dependencies]
rich_err = "0.1.0"

Example Usage

Here's a basic example demonstrating how to use rich_err:

use rich_err::RichError;

fn main() {
    let error = RichError::new("An error occurred")
        .with_context("Failed to open file")
        .with_context("Permission denied");

    println!("{}", error.to_string_with_context());
}

Output:

An error occurred Context: Failed to open file Context: Permission denied
