# MB.FastAutoMapper

The aim of this project is to provide compile-time support for auto-mapping by using source generation. The ubiquitous AutoMapper instead builds the mapping code at run-time.

One of the benefits of this approach, besides paying the mapping cost at compile-time instead of run-time everytime, is that any mapping errors are also caught at compile time due to the strict type-safety of C#. 

The code is pretty simple to use, simply reference the NuGet package `MB.FastAutoMapper` and write something like this:

```C#

using FastAutoMapper;

class Src

{

  public string Text { get; set; }

  public float[] Color { get; set; }

}

class Dst

{

  public string Text { get; set; }

  public Vector3 Color { get; set; }

}

// first declare the mapper class, make sure it is a partial type

partial class Mapper : FastAutoMapperBase { }

// then declare your instance

var mapper = new Mapper();

// define the maps you need, including any conversions with `ForMember`

mapper.CreateMap()

  .ForMember(x => x.Color, x => new Vector3(x.Color[0], x.Color[1], x.Color[2]));

  

// and map your instances

var dst = mapper.Map(new Src { Text = "meep", Color = new[] { .1f, .5f, 1f } });

```
