Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TwirpError(TwirpError)

A standard Twirp error with a type, message, and some metadata

JsonDecodeError(Error)

An error when trying to decode JSON into an error or object

ProstEncodeError(EncodeError)

An error when trying to encode a protobuf object

ProstDecodeError(DecodeError)

An error when trying to decode a protobuf object

HyperError(Error)

A generic hyper error

HttpError(Error)

A HTTP protocol error

InvalidUri(InvalidUri)

An invalid URI.

InvalidMethod

The HTTP Method was not POST.

InvalidContentType

The request content type was not application/protobuf.

NotFound

No matching method was found for the request.

AfterBodyError

A wrapper for any of the other ProstTwirpErrors that also includes request/response info

Fields

§body: Vec<u8>

The request or response’s raw body before the error happened

§method: Option<Method>

The request method, only present for server errors

§version: Version

The request or response’s HTTP version

§headers: HeaderMap

The request or response’s headers

§status: Option<StatusCode>

The response status, only present for client errors

§err: Box<ProstTwirpError>

The underlying error
