Mapped type "PartialType"

[ByteSturm]

Hey @nartc,
in my NestJS project I use for my update DTOs often the mapped type "PartialType" like in the following example:
export class UpdateCatDto extends PartialType(CreateCatDto) {}

When looking at the documentation of automapper, I saw that there do exist mapped types too. I know the NestJS "PartialType" is from the @nestjs/swagger package. Would it make sense to add this "PartialType" functionality to automapper? (At best compatible to the @nestjs/swagger package 😄 )

The benefit would be not having to define the update DTOs explicitly if they are identical as the create DTOs, just all properties being optional.

Hey @ByteSturm, it is actually a blocker on my end as I'm not sure how to compose the mixin (the mapped types) in a type-safe way #271
