dto_derive's Issues

fix: skip attr on a response dto should emit more informative error

refactor: improve `container` code

Rethink container implementation.

feat: add complex entity mapping

#[derive(Dto)]
#[dto(entity = "Entity", with = "String, Uuid")]
struct Dto {
...
}

feat: only first error is returned

Return as many errors as possible.
Maybe use: https://github.com/JoshMcguigan/multi_try

feat: add mapping via closure

#[derive(Dto)]
#[dto(map = "a: |dto| dto.b")]
struct Dto {
...
}

feat: add mapping via function call

#[derive(Dto)]
#[dto(map = "a: Uuid::new_v4()")]
struct Dto {
...
}

this error originates in the derive macro `Dto`

pub struct PostVo{
title:String,
body:String
}

use dto_derive::Dto;
use crate::vo::post::PostVo;
#[derive(Dto)]
#[dto(request)]
#[dto(entity="PostVo")]
#[dto(map="body:content")]
#[dto(skip = "csrf_token")]
pub struct NewPost{
pub(crate) title:String,
pub(crate) content:String,
pub(crate) csrf_token:String,
}

#[derive(Dto)]
| ^^^ private field
|
= note: this error originates in the derive macro Dto (in Nightly builds, run with -Z macro-backtrace for more info)

feat: improve checking of mappings

Emit errors when:

there is a mapping for the same field
there is no such field

feat: add nested fields mapping

#[derive(Dto)]
#[dto(map = "a: b.c.d.e")]
struct Dto {
...
}
