# funlog

[简体中文](README.zh-CN.md) | English

A procedural macro for tracing Rust function calls.

## Features

- Automatically trace function entry and exit
- Log function parameters and return values
- Easy integration with the standard Rust logging system
- Minimal performance overhead

## Installation

Add this to your `Cargo.toml`:

```toml
[dependencies]
funlog = "0.1.0"
```

## Usage

```rust
use funlog::trace;

#[trace]
fn example_function(x: i32) -> i32 {
    x + 1
}
```

## Configuration

The macro uses the standard Rust `log` crate. Make sure to initialize a logger (such as `env_logger`) in your application.
