Riok.Mapperly 3.1.0
Mapperly
Mapperly is a .NET source generator for generating object mappings. Inspired by MapStruct.
Because Mapperly creates the mapping code at build time, there is minimal overhead at runtime. Even better, the generated code is perfectly readable, allowing you to verify the generated mapping code easily.
Documentation
The documentation is available here.
Quickstart
Installation
Add the NuGet Package to your project:
dotnet add package Riok.Mapperly
Create your first mapper
Create a mapper declaration as a partial class
and apply the Riok.Mapperly.Abstractions.MapperAttribute attribute.
Mapperly generates mapping method implementations for the defined mapping methods in the mapper.
// Mapper declaration
[Mapper]
public partial class CarMapper
{
public partial CarDto CarToCarDto(Car car);
}
// Mapper usage
var mapper = new CarMapper();
var car = new Car { NumberOfSeats = 10, ... };
var dto = mapper.CarToCarDto(car);
dto.NumberOfSeats.Should().Be(10);
