Errors produced by dvgw-edi.

All public API entry points return Result<_, Error>.

Variants (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.

Parse(EdifactError)

The underlying EDIFACT tokeniser rejected the input.

Serialize(String)

Rendering an outbound message back to EDIFACT bytes failed.

MissingSegment(&'static str)

A segment the DVGW Nachrichtenbeschreibung marks Muss is absent, so the message cannot even be identified.

UnknownDocumentCode

BGM C002 DE 1001 does not carry a document-name code this crate knows.

DVGW identifies the logical message (ALOCAT / NOMINT / NOMRES) by this code — not by the UNH message type, which is always the UN/EDIFACT carrier ORDERS or ORDRSP.

The raw code is kept out of Display so an untrusted value cannot reach operator logs; read it from raw_code when diagnosing.

Fields

raw_code: String

The sanitized BGM DE 1001 value.

CarrierMismatch

UNH S009 DE 0065 names a carrier that does not match the document code.

NOMINT rides ORDERS; ALOCAT and NOMRES ride ORDRSP. A mismatch means the two identifying fields disagree, which no conformant sender produces.

Fields

document: &'static str

The BGM DE 1001 code that was read.

expected: &'static str

The carrier that code requires.

raw_code: String

The sanitized UNH DE 0065 value that was found instead.

Io(Error)

A wrapped I/O error from the reader-based entry points.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<EdifactError> for Error

fn from(source: EdifactError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
