Errors that can occur when using the Mapper API.

Variants

DataDirNotFound

The specified data directory does not exist on disk.

Fields

path: String

BundleNotFound

No data bundle file found for the requested format version.

Fields

fv: String

VariantNotFound

The requested variant (e.g., “UTILMD_Strom”) is not present in the bundle.

Fields

fv: String

variant: String

PidNotFound

No mapping engine definitions exist for the given PID within the variant.

Fields

fv: String

variant: String

pid: String

Assembly(AssemblyError)

An error from the MIG assembly layer.

Mapping(MappingError)

An error from the TOML mapping engine.

Serialization(String)

JSON serialization failed (e.g., when converting a typed struct to JSON).

NoMigSchema

The variant has no MIG schema (required for reverse pipeline).

Fields

fv: String

variant: String

MissingGroupEntrySegment(Box<GroupEntrySegmentError>)

The BO4E input fills a group’s segments but not the segment that opens the group in the MIG (e.g. Zaehler.geraeteNummer without Zaehler.zaehlertypMerkmal would yield SG10 CAV without CCI). Rendering it would produce EDIFACT no receiver can assemble, so the conversion is refused. Boxed to keep MapperError small.

Io(Error)

A standard I/O error.

Trait Implementations

impl Debug for MapperError

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

Formats the value using the given formatter.

impl Display for MapperError

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

Formats the value using the given formatter.

impl Error for MapperError

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<AssemblyError> for MapperError

fn from(source: AssemblyError) -> Self

Converts to this type from the input type.

impl From<Error> for MapperError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<MappingError> for MapperError

fn from(source: MappingError) -> Self

Converts to this type from the input type.
