Astarte error.

Possible errors returned by functions of the Astarte device SDK.

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.

ConnectionTimeout

The connection poll reached the max number of retries.

Interface(Error)

Error while parsing interface.

AddInterface(AddInterfaceError)

Error while operating on the device introspection.

InterfaceNotFound

Couldn’t find an interface with the given name.

Fields

name: String

Name of the missing interface.

MappingNotFound

Couldn’t find missing mapping in the interface.

Fields

interface: String

Name of the interface.

mapping: String

Path of the missing mapping.

InvalidEndpoint(MappingPathError)

Couldn’t parse the mapping path.

Types(TypeError)

Errors when converting between Astarte types.

Properties(PropertiesError)

Error while parsing the /control/consumer/properties payload.

Store(StoreError)

Error returned by a store operation.

Validation(UserValidationError)

Send or receive validation failed

Aggregation(AggregationError)

Invalid aggregation between the interface and the data.

InterfaceType(InterfaceTypeError)

Invalid interface type between the interface and the data.

Builder(BuilderError)

Couldn’t build the device connection and client

Mqtt(MqttError)

Error returned by the MQTT connection.

Disconnected

Error when the Device is disconnected from Astarte or client.

This is an unrecoverable error for the SDK.

Retention(RetentionError)

Retention operation failed.

Session(SessionError)

Persistent session operation failed

Grpc(GrpcError)

Available on crate feature message-hub only.

Error returned by the gRPC transport

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
