I have followed the above transaction formats. The signed raw transaction follows the specification given in bicoin developers raw transaction format.

Given are the implementation codes in Rust

fn get_txid(inputs: Vec<Vec<u8>>, outputs: Vec<Vec<u8>>) -> [u8; 32] {
    let mut tx = Vec::new();

    //adding version
    let version: u32 = 0x00000002;
    tx.extend_from_slice(&version.to_le_bytes());

    let inputs_length: u32 = inputs.len() as u32;
    tx.extend_from_slice(&inputs_length.to_le_bytes());

    for input in inputs {
        tx.extend_from_slice(&input);
    }

    let outputs_length: u32 = outputs.len() as u32;
    tx.extend_from_slice(&outputs_length.to_le_bytes());

    for output in outputs {
        tx.extend_from_slice(&output);
    }

    let locktime: u32 = 0x00000000;
    tx.extend_from_slice(&locktime.to_le_bytes());
    let txid = sha256_hash(&sha256_hash(&tx));
    //output

    let tx_array: [u8; 32] = match txid.try_into() {
        Ok(arr) => arr,
        Err(_) => panic!("Expected a Vec of length 32, but it was {}", tx.len()),
    };

    // reverse txid
    let mut reversed_txid = [0; 32];
    for i in 0..32 {
        reversed_txid[i] = tx_array[31 - i];
    }

    reversed_txid
}

Output serialization

fn output_from_options(script: &[u8], value: u32) -> Vec<u8> {
    
    let mut output = Vec::new();
    let valhue: u64 = value as u64;
    let value_in_8_bytes_in_little_endian = valhue.to_le_bytes();
    output.extend_from_slice(&value_in_8_bytes_in_little_endian);

    let script_length = script.len() as u64; 
    let script_length_varint = turn_to_varint(script_length);
    
    output.extend_from_slice(&script_length_varint);
    output.extend_from_slice(script); //scriptpubkey {p2wpkh and p2wsh}
    output

    //OK
}

Input Serialization

fn input_from_utxo(txid: &[u8], index: u32) -> Vec<u8> {
    let mut input = Vec::new();

    //txid
    let reversed_txid: Vec<u8> = txid.iter().rev().cloned().collect();
    input.extend_from_slice(&reversed_txid);

    //index
    let index_in_little_endian_bytes = index.to_le_bytes();  // fixed 4 bytes
    input.extend_from_slice(&index_in_little_endian_bytes);
    
    //script length (default is zero for us)
    input.push(0x00);

    //sequence
    let sequence: u32 = 0xffffffff;
    input.extend_from_slice(&sequence.to_le_bytes());

    input

    //OK
}
