# ✨ Features

```toml
```

# 📖 Example

```toml
[dependencies]
e-macros = "0.1"
```

```rust
#[derive(e_macros::C)]

struct B {
  d: i32,
  f: String,
}
fn test() -> Result<()> {
  // 假设我们有一个T类型的实例
  let value: B = B {
    d: 1,
    f: "test".to_string(),
  };
  let ptr = value.to_c_ptr();
  // 还原*c_void指针为<Box<T>>实例
  if let Some(restored_boxed_value) = unsafe { B::from_c_ptr(ptr) } {
    // 成功还原Box<T>实例
    println!("Restored value: {:?}", *restored_boxed_value);
  } else {
    // 还原过程中出现错误
    println!("Failed to restore value");
  }
  Ok(())
}
```
# 智能写入Json

# Example

```rust
#[derive(serde::Deserialize, Debug, serde::Serialize, Default, e_macros::Json)]

struct B {
  d: i32,
  f: String,
}
fn test() {
  let mut b: B = B::default();
  b.f = "test".to_string();
  b.auto_write_json(Path::new("."), "test.json").unwrap();
  let b = B::auto_read_json(Path::new("test.json")).unwrap();
  println!("B {:?}", b);
}
```
# 智能读取Json

# Example

```rust
#[derive(serde::Deserialize, Debug, serde::Serialize, Default, e_utils::Json)]

struct B {
  d: i32,
  f: String,
}
fn test() {
  let mut b: B = B::default();
  b.f = "test".to_string();
  b.auto_write_json(Path::new("."), "test.json").unwrap();
  let b = B::auto_read_json(Path::new("test.json")).unwrap();
  println!("B {:?}", b);
}
```
# 安全地还原*const c_void指针为Box<Self>
# Example
```rust
#[derive(e_utils::C)]
struct B {
  d: i32,
  f: String,
}
fn test() -> Result<()> {
  // 假设我们有一个T类型的实例
  let value: B = B {
    d: 1,
    f: "test".to_string(),
  };
  let ptr = value.to_c_ptr();
  // 还原*c_void指针为<Box<T>>实例
  if let Some(restored_boxed_value) = unsafe { B::from_c_ptr(ptr) } {
    // 成功还原Box<T>实例
    println!("Restored value: {:?}", *restored_boxed_value);
  } else {
    // 还原过程中出现错误
    println!("Failed to restore value");
  }
  Ok(())
}
```

## `💡!important：`

<!-- ####There are three requirements for building on the windows system environment:

You must use the rust version using the MSVC toolchain

You must install [WinPcap]（ https://www.winpcap.org/ ）Or [npcap]（ https://nmap.org/npcap/ ）(using [WinPcap]（ https://www.winpcap.org/ ）Version 4.1.3) (if using [npcap]（ https://nmap.org/npcap/ ）, please make sure to use "in [WinPcap]（ https://www.winpcap.org/ ）Install [npcap] in API compatibility mode（ https://nmap.org/npcap/ )”）

You must put it in your bag. [WinPcap]( https://www.winpcap.org/ ）The Lib in the developer package is located in the directory named Lib in the root directory of the repository. Alternatively, you can use any location listed in the% lib% / $env: lib environment variable. For the 64 bit toolchain, it is located in wpdpack / lib / x64 / packet. For the 32-bit toolchain, it is located in wpdpack / lib / packet.lib.
```
# 1.install npcap server https://npcap.com/dist/npcap-1.70.exe
setx LIB E:\libs\LIB
# download and decompression https://npcap.com/dist/npcap-sdk-1.13.zip
# npcap-sdk-1.13\Lib\x64\Packet.lib put to E:\libs\LIB
``` -->


# 🚀 fast running

<!-- ```sh
# host/port scan
cargo run --example host_scan
cargo run --example port_scan
# async scan
cargo run --example async_host_scan --features="async"
cargo run --example async_port_scan --features="async"
# Fingerprint scan
cargo run --example os --features="os"
# Service Scan
cargo run --example service_detection --features="service"
# DNS Parse
cargo run --example dns
# Trace Route
cargo run --example tracert
``` -->


# 🦊 Applied Projects

<!-- [E-NetScan](https://github.com/EternalNight996/e-netscan.git): The network scanning project (which supports both command line and cross platform graphical interface) is under development.. -->


# 🔭 why need to e-utils?

<!-- At first, I wanted to complete a cross network scanning project to help me complete some work. I referred to many open source projects, but these projects have some defects that do not meet my needs, so I have e-libscanner.
(process host and port scanning, and support domain name resolution, route tracking, fingerprint scanning, service scanning, asynchronous scanning, scalability and more)
The bottom layer is by calling [npcap]（ https://nmap.org/npcap/ ）And [WinPcap]（ https://www.winpcap.org/ ）Packet capture service;
The service API is [libpnet]（ https://github.com/libpnet/libpnet ); -->
