Animagi

A smart object mapper for Golang structures.

Feature list

• handles copy of same Types and aliased Types
• handles nested structures
• handles pointers
  • primitive types to pointer of the same type (new memory allocated for pointer): int -> *int
  • pointer of primitive to the primitive type: *string -> string
  • pointer of primitive to pointer of primitive (deep copy, new memory allocated): *uint -> *uint
  • all of the above where the types are aliased: myint -> *int or *mystring -> string, etc.

Usage

The Transform method takes in a source and destination. The source will be mapped to the destination which means the destination must be settable (pass a pointer to the variable).

type mystring string
type myint int

src := struct {
    A int
    B mystring
    C string
}{42, "a string", "just another string"}

var dst struct {
    A myint
    B string
    D uint8
}

err := animagi.Transform(src, &dst)

In the above dst will have A and B set to 42 and a string and D will be default value of 0.
