Enum DiscoveryError

pub enum DiscoveryError {
    ModbusError(ModbusError),
    SunsIdentifierNotFound,
    AddressOverflow,
}

This error is returned when an error occurs during model discovery.

Variants

ModbusError(ModbusError)

Communication error.

SunsIdentifierNotFound

The Modbus slave did not provide the “SunS” header at the well known addresses 0, 40000 or 50000.

AddressOverflow

The addresses would overflow while discovering modules. The slave device seams to be returning garbage data.

Trait Implementations

impl Debug for DiscoveryError

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

Formats the value using the given formatter.

impl Display for DiscoveryError

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

impl Error for DiscoveryError

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<ModbusError> for DiscoveryError

fn from(source: ModbusError) -> Self

Converts to this type from the input type.
