expected type, found module *** not a type

[futugyou]

I have a struct like this, and it was working normally.

#[derive(Debug, Default, Validate, Serialize, Deserialize)]
pub struct AnimalInsertRequest {
    #[serde(with = "date_format", default)]
    pub rescue_date: Option<DateTime<Utc>>,
}

but when add 'JsonSchema' like this

#[derive(Debug, Default, Validate, Serialize, Deserialize, ApiComponent, JsonSchema)]
pub struct AnimalInsertRequest {
    #[serde(with = "date_format", default)]
    pub rescue_date: Option<DateTime<Utc>>,
}

it show an error,

error[E0573]: expected type, found module `date_format`
#[serde(with = "date_format", default)]
                  ^^^^^^^^^^^^^ not a type

what can i do with this error

Hi, thanks for the report !
What version of apistos / schemars do you use ?
This is most likely an issue on schemars side and not directly related to apistos.
Just in case, please make sure your serde version match the one provided by schemars, it could explain the issue.

[futugyou]

schemars = { package = "apistos-schemars", version = "0.8", features = [
    "chrono",
    "uuid1",
    "url",
    "rust_decimal",
] }
apistos = { version = "0.3", features = [
    "extras",
    "qs_query",
    "rapidoc",
    "redoc",
    "swagger-ui",
] }

Reference here

I also tried the default features, same error.

schemars = { package = "apistos-schemars", version = "0.8" }
apistos = { version = "0.3" }

And i found another question, this is metrics endpoint.

#[get("/metrics")]
#[api_operation(summary = "health check")]
pub(crate) async fn metrics(metrics_handle: ThinData<PrometheusHandle>) -> impl Responder {
    metrics_handle.render()
}

ThinData in actix-web 4.9
PrometheusHandle in metrics-exporter-prometheus 0.15.3

this code show an error

no function or associated item named `required` found for struct `ThinData<PrometheusHandle>` in the current scope
function or associated item not found in `ThinData<PrometheusHandle>`

Hi,
I still can't figure out the issue.

About this snippet:
#[get("/metrics")] #[api_operation(summary = "health check")] pub(crate) async fn metrics(metrics_handle: ThinData<PrometheusHandle>) -> impl Responder { metrics_handle.render() }

• Apistos currently does implement ApiComponent for ThinData nor PrometheusHandle. It could be done and hidden behind a feature
• actix macros (#[get(...)] for example) are currently not supported by Apistos. This would generate an incorrect definition with no path.
