Rust PE文件解析库pelite-macros的使用

pelite-macros为pelite crate提供了过程宏的实现。这个库本身不需要直接使用，当你依赖pelite时它会自动被导入。

安装

在你的项目目录中运行以下Cargo命令：

cargo add pelite-macros

或者在Cargo.toml中添加以下行：

pelite-macros = "0.1.1"

完整示例

虽然pelite-macros通常不需要直接使用，但以下是使用pelite库解析PE文件的基本示例：

use pelite::pe64::{Pe, PeFile};

fn main() -> Result<(), pelite::Error> {
    // 读取PE文件
    let bytes = std::fs::read("example.exe")?;
    
    // 解析PE文件
    let pe_file = PeFile::from_bytes(&bytes)?;
    
    // 获取DOS头
    let dos_header = pe_file.dos_header();
    println!("DOS header magic: {:#X}", dos_header.magic);
    
    // 获取NT头
    let nt_headers = pe_file.nt_headers();
    println!("PE signature: {:#X}", nt_headers.Signature);
    println!("Number of sections: {}", nt_headers.FileHeader.NumberOfSections);
    
    // 遍历所有节区
    for section in pe_file.section_headers() {
        println!("Section: {}", String::from_utf8_lossy(&section.Name));
        println!("Virtual size: {:#X}", section.VirtualSize);
        println!("Virtual address: {:#X}", section.VirtualAddress);
    }
    
    Ok(())
}

许可证

pelite-macros使用MIT许可证。

更完整示例

基于上述示例，这里提供一个更完整的PE文件解析demo，包含更多PE文件信息的提取：

use pelite::pe64::{Pe, PeFile};
use pelite::util::CStr;

fn main() -> Result<(), pelite::Error> {
    // 读取PE文件
    let bytes = std::fs::read("example.exe")?;
    
    // 解析PE文件
    let pe_file = PeFile::from_bytes(&bytes)?;
    
    // 1. 打印DOS头信息
    let dos_header = pe_file.dos_header();
    println!("[DOS Header]");
    println!("Magic: {:#X}", dos_header.magic);
    println!("PE Offset: {:#X}", dos_header.pe_offset);
    
    // 2. 打印NT头信息
    let nt_headers = pe_file.nt_headers();
    println!("\n[NT Headers]");
    println!("Signature: {:#X}", nt_headers.Signature);
    println!("Machine: {:#X}", nt_headers.FileHeader.Machine);
    println!("Number of Sections: {}", nt_headers.FileHeader.NumberOfSections);
    println!("TimeDateStamp: {:#X}", nt_headers.FileHeader.TimeDateStamp);
    
    // 3. 打印可选头信息
    let opt_header = nt_headers.OptionalHeader;
    println!("\n[Optional Header]");
    println!("Magic: {:#X}", opt_header.Magic);
    println!("EntryPoint: {:#X}", opt_header.AddressOfEntryPoint);
    println!("ImageBase: {:#X}", opt_header.ImageBase);
    println!("Size of Image: {:#X}", opt_header.SizeOfImage);
    
    // 4. 打印所有节区信息
    println!("\n[Section Headers]");
    for section in pe_file.section_headers() {
        let name = String::from_utf8_lossy(&section.Name);
        println!("\nSection: {}", name.trim_end_matches('\0'));
        println!("VirtualSize: {:#X}", section.VirtualSize);
        println!("VirtualAddress: {:#X}", section.VirtualAddress);
        println!("RawSize: {:#X}", section.SizeOfRawData);
        println!("RawAddress: {:#X}", section.PointerToRawData);
        println!("Characteristics: {:#X}", section.Characteristics);
    }
    
    // 5. 尝试获取导出表信息
    if let Ok(export) = pe_file.exports() {
        println!("\n[Exports]");
        println!("Name: {}", String::from_utf8_lossy(export.name()?));
        println!("Base: {}", export.base());
        println!("Count: {}", export.count());
        
        for export in export {
            let export = export?;
            println!("\nExport: {}", String::from_utf8_lossy(export.name()?));
            println!("Ordinal: {}", export.ordinal());
            println!("RVA: {:#X}", export.rva());
        }
    }
    
    Ok(())
}
