cannot unmarshal string into Go struct field Disk.Blocks.disks.drive_type of type block.DriveType

[Techno-Fox]

I was trying to marshal and unmarshal data, but then this comes up. I believe it's because DriveType is an int, while the marshaled version is a string, because of the MarshalJSON function converting it to a string.

Proposal: Add an UnmarshalJSON function to types that are converted from the original. To be converted back their original type for unmarshaling.

Please correct me if I'm wrong!

Hi! could you please provide a simple reproducer to fully understand the flow?

package main

import (
    "encoding/json"
    "log"

    "github.com/jaypipes/ghw"
)

func main() {
    blocks, err := ghw.Block(ghw.WithDisableWarnings())
    if err != nil {
        log.Fatal(err)
    }

    data, err := json.Marshal(blocks)
    if err != nil {
        log.Fatal(err)
    }

    var bi *ghw.BlockInfo
    err = json.Unmarshal(data, &bi)
    if err != nil {
        log.Fatal(err)
    }
}
