Struct StrictJsonOrForm 

pub struct StrictJsonOrForm<T>(pub T);

JsonOrForm that refuses a JSON body carrying a key the target type does not take.

The keys a record’s own response carries but no write takes — id, metadata and the created_at / updated_at / deleted_at timestamps, in either casing — are tolerated, so a client that sends back the record it read is not refused for them. Form bodies stay lenient: a browser form posts its buttons and hidden inputs too.

impl<S, T> FromRequest<S> for StrictJsonOrForm<T>

where S: Send + Sync, T: DeserializeOwned + 'static,

type Rejection = Response<Body>

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

fn from_request<'life0, 'async_trait>( req: Request, state: &'life0 S, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Perform the extraction.
