[Questions] Does the generated code need optimization?

Have you read the project readme?

[x] Yes, but it does not include related information regarding my question.
[x] Yes, but the steps described do not work.
[x] Yes, but I am having difficulty understanding it and want clarification.

Describe your question A clear and concise description of what the question is. Include errors and go source files.

type Tx int

type In struct {
    A Tx
}
type Out struct {
    A Tx
}

// goverter:converter
type Converter interface {
    Convert(in constructor.In) (constructor.Out, error)
    ConvertList(in []constructor.In) ([]constructor.Out, error)
}

result: generated.go

// Code generated by github.com/jmattheis/goverter, DO NOT EDIT.

package generated

import (
    "fmt"
    constructor "xxx/constructor"
)

type ConverterImpl struct{}

func (c *ConverterImpl) Convert(source constructor.In) (constructor.Out, error) {
    var constructorOut constructor.Out
    constructorOut.A = constructor.Tx(source.A)
    return constructorOut, nil
}
func (c *ConverterImpl) ConvertList(source []constructor.In) ([]constructor.Out, error) {
    var constructorOutList []constructor.Out
    if source != nil {
        constructorOutList = make([]constructor.Out, len(source))
        for i := 0; i < len(source); i++ {
            constructorOut, err := c.Convert(source[i])
            if err != nil {
                var errValue []constructor.Out
                return errValue, fmt.Errorf("error setting index %d: %w", i, err)
            }
            constructorOutList[i] = constructorOut
        }
    }
    return constructorOutList, nil
}

The field type is related, they are all Tx, just assign directly? No forced conversion required?
If it is a slice, len(source) is used twice, use the variable to receive, reduce the number of calls?
