Enum rustdds::dds::result::ReadError

    Deserialization {
        reason: String,
    },

        details: String,
    },

}

Error type for DDS “read” type operations.

Variants

Deserialization

Fields

reason: String

Data received over RTPS could not be decoded. Reason field gives more details on what went wrong.

UnknownKey

Fields

details: String

DDS received a data instance dispose message via RTPS, but was asked to dispose an instance, which we do not have.

If that data instance was published and last available for reading before this DataReader joined the domain (i.e. was started), then it is normal that we do not know it. Otherwise, it could be a symptom of communication or serialization error.

Poisoned

Fields

reason: String

Communication or synchronization with RTPS processing thread or Discovery thread fails. This is most likely because either thread has panicked or gotten stuck somewhere, neither of which is supposed to happen. This is typically not recoverable, except by starting a new DomainParticipant.

Internal

Fields

reason: String

Something that should not go wrong went wrong anyway. This is usually a bug in RustDDS

Trait Implementations

impl Debug for ReadError

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

Formats the value using the given formatter.

impl Display for ReadError

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

Formats the value using the given formatter.

impl Error for ReadError

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

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.
