Enum Error 

pub enum Error<T> {
    Transport(T),
    DeviceNotFound,
    PointNotFound,
    MeasurandNotSupported,
    AmbiguousMeasurand,
    UnsupportedMapping(&'static str),
    Decode(DecodeError),
    Encode(EncodeError),
    WriteAccess,
    WriteConstraint(ConstraintKind),
}

Facade error, generic over the transport’s error type.

Variants

Transport(T)

DeviceNotFound

PointNotFound

MeasurandNotSupported

AmbiguousMeasurand

More than one point matches the measurand query (spec §26.4).

UnsupportedMapping(&'static str)

Composed points via facade, unknown discovery kind, SunS not found…

Decode(DecodeError)

Encode(EncodeError)

WriteAccess

WriteConstraint(ConstraintKind)

Trait Implementations

impl<T: Debug> Debug for Error<T>

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

Formats the value using the given formatter.

impl<T: Display> Display for Error<T>

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

Formats the value using the given formatter.

impl<T: Display + Debug> Error for Error<T>

Available on crate feature std only.

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<T> From<DecodeError> for Error<T>

fn from(e: DecodeError) -> Self

Converts to this type from the input type.

impl<T> From<EncodeError> for Error<T>

fn from(e: EncodeError) -> Self

Converts to this type from the input type.
