I have made a rust webserver using Warp. When I send a request to the webserver, it cannot deserialize the given body. I know exactly why this error happens, and am not asking about how to fix the deserializatin error. The issue that I have is that nothing is logged when this error occurs. I would like to learn how to generate logs for an error of this kind.
The router function for the route in question is here:
pub fn put_order(repo: data::Repository) -> impl Filter<Extract = impl Reply, Error = Rejection> + Clone {
warp::path("orders")
.and(warp::path("v1"))
.and(warp::put())
.and(with_order_body())
.and(with_repo(repo))
.and_then(orders::put)
}
The with_order_body() function in particular is the one that I believe is throwing the error with deserialization:
fn with_order_body() -> impl Filter<Extract = (model::Order,), Error = Rejection> + Clone {
warp::body::content_length_limit(1024 * 16).and(warp::body::json())
}
The Order type is defined (and it is supposed to be a CouchDB document using the couch_rs package, in case you were wondering) :
#[derive(Debug, Serialize, Deserialize, Clone, CouchDocument)]
pub struct Order {
#[serde(skip_serializing_if = "String::is_empty")]
_id: DocumentId,
#[serde(skip_serializing_if = "String::is_empty")]
_rev: String,
items: Vec<OrderItem>,
user_token: String,
payment_token: String,
}
The error that results is returned when I curl my webserver, but not logged:
Request body deserialize error: missing field `_rev` at line 24 column 1
The request payload, you may not be surprised to find, is a 24 line JSON payload; the error "points" to the closing bracket on the JSON payload.
How can I get this log to be returned at command line when I run my webserver locally, in addition to being returned as an error to the remote caller.
