How to extract struct in query params?

[CharlieBytesX]

Hi, in dotnet i can do (just for the example)

    public async Task<
        ActionResult<OutputDtos.PagedResponse<List<OutputDtos.ChainGroupedDto>>>
    > GetChain(
        [FromQuery] InputDtos.PaginationParams paginationParams,
        [FromQuery] string? sortOrder = null,
        [FromQuery] string? name = null
    )
//{...}

In poem open api im trying to do the same by passing a struct:

    #[oai(path = "/chain", method = "get")]
    async fn get_chains(
        &self,
        state: Data<&AppState>,
        pagination_params: Query<input_dto::PaginationParams>,
    ) {
        todo!()
    }

This is paginations params:

#[derive(Object, Debug, Serialize)]
pub struct PaginationParams {
    pub page_number: u32,
    pub page_size: u32,
}

I'm getting this error:

Diagnostics:
1. the trait bound `Query<PaginationParams>: ApiExtractor<'_>` is not satisfied
   the trait `poem_openapi::ApiExtractor<'_>` is not implemented for `poem_openapi::param::Query<domain::cqp::chain::input_dto::PaginationParams>`

What I'm missing, thanks for the help

I'm trying the same and having no luck with finding a solution. I tried implementing ApiExtractor for Query, but I'm getting the orphan rule compiler error.

Query only supports simple types, not objects.

Thanks! Is there any way I can add the functionality for a complex type in my application code or it's not supported at all?

Great work with the framework 🔝
