Adapters

Adapt

Use the adapt package to convert between common structures.

Using JSON Struct Tags

This converts between structs using the JSON struct tags on each object.

package main

import "github.com/inventorandy/convertr/adapt"

type StructA struct {
  ID int64 `json:"id"`
  Name string `json:"name"`
}

type StructB struct {
  ID int `json:"id"`
  Name *string `json:"name"`
}

func main() {
  // Struct to Convert From
  from := StructA{1234, "Hello, World!"}

  // Struct to Convert To
  var to StructB

  // Convert the Structs
  if err := adapt.UsingJSON(from, &to); err != nil {
    log.Fatalln(err)
  }
}

Pointers

Use the ptr package to easily convert between types and pointers.

Example Usage

package main

import "github.com/inventorandy/convertr/ptr"

func main() {
  // Create a Pointer to a String
  str := "Hello, World"
  strPtr := ptr.To(str) // Returns *string

  // Convert back to a String
  newStr := ptr.From(strPtr) // Returns string
}
