You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: error.rs
    path of file: ./repos/ckb/util/types/src/core
    
    the code of the file until where you have to start completion: //! The error types to unexpected out-points.

use crate::{
    core::{Capacity, Version},
    packed::{Byte32, OutPoint},
};
use ckb_error::{impl_error_conversion_with_kind, prelude::*, Error, ErrorKind};
use derive_more::Display;

/// Errors due to the fact that the out-point rules are not respected.
#[derive(Error, Debug, PartialEq, Eq, Clone)]
pub enum OutPointError {
    /// The target cell was already dead.
    #[error("Dead({0:?})")]
    Dead(OutPoint)
    
    pub fn is_malformed_tx(&self) -> bool {
        match self {
