DES-ECB encryption does not appear to be standard encryption

[XiEdAotonG]

Encryption results differ from des = "0.8"
This is the code and result of the minimum implementation
Code:

use des::{
    cipher::{BlockEncrypt, KeyInit},
    Des,
};
use ruscrypt::block::des as ruscryptdes;
fn main() {
    let data = "abcdefg";
    let key = "00000000";
    // use ruscrypt: Encrypt with  DES-ECB
    let encrypted = ruscryptdes::encrypt(data, key, "ECB", "hex").unwrap();
    println!("Encrypt with ruscrypt DES-ECB :{:?}", encrypted);
    // use des: Encrypt with DES-ECB
    let encrypted = encrypt(key, data);
    println!("Encrypt with des DES-ECB :{:?}", encrypted.unwrap());
}
fn pkcs7_pad(data: &[u8], block_size: usize) -> Vec<u8> {
    let padding_len = block_size - (data.len() % block_size);
    let mut padded = data.to_vec();
    padded.extend(vec![padding_len as u8; padding_len]);
    padded
}
fn encrypt(key: &str, text: &str) -> Result<String, String> {
    let key: &[u8] = key.as_bytes();
    let data = text.as_bytes();

    let mut encrypted = Vec::new();
    let cipher = Des::new(key.into());
    let padded_data = pkcs7_pad(data, 8);
    for chunk in padded_data.chunks(8) {
        let mut block = des::cipher::generic_array::GenericArray::clone_from_slice(chunk);
        cipher.encrypt_block(&mut block);
        encrypted.extend_from_slice(&block);
    }
    Ok(hex::encode(encrypted))
}

Result：

Encrypt with ruscrypt DES-ECB :"f6f769f973fb3b1c"
Encrypt with des DES-ECB :"162ab71c485c6c5c"
