使用nom读取二进制u32

use nom::{
    IResult,
    bytes::complete::{take},
    number::complete::{be_u32},
};

fn parse_u32(input: &[u8]) -> IResult<&[u8], u32> {
    let (remaining, bytes) = take(4usize)(input)?;
    let value = be_u32(bytes)?;
    Ok((remaining, value))
}

fn main() {
    let data = [0x01, 0x00, 0x00, 0x00]; // 二进制表示的 1
    match parse_u32(&data) {
        Ok((remaining, value)) => {
            println!("Parsed value: {}", value);
            println!("Remaining data: {:?}", remaining);
        },
        Err(e) => {
            eprintln!("Error parsing u32: {:?}", e);
        }
    }
}

let result = parse_u32(&data);
match result {

    },
    Err(e) => {
        eprintln!("Error parsing u32: {:?}", e);
        // 进一步调试错误
        if let nom::Err::Error(err) = e {
            println!("Error kind: {:?}", err.kind);
