How to mark optional query string?

[theanh098]

My query struct

#[derive(Deserialize, IntoParams, Validate)]
pub struct QueryString {
  #[validate(range(min = 1))]
  limit: u32,

  r#type: Option<String>,

  main_category: Option<String>,

}

And on swagger ui type and main_category that are required. How to mark its is optional?

Hey, this is related to issue #622. The properties should be nullable by default when Option is used, but it seems that there is some bug that causes properties to be required.

Others has solved this with providing manually the parameter_in = Query attribute for the IntoParams macro.
