Implementations

impl ModbusError

pub fn to_exception_code(&self) -> u8

Convert to Modbus exception code.

pub fn invalid_address(address: u16, max: u16) -> Self

Create an invalid address error.

pub fn invalid_quantity(quantity: u16, max: u16) -> Self

Create an invalid quantity error.

Trait Implementations

impl Debug for ModbusError

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

Formats the value using the given formatter.

impl Display for ModbusError

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

Formats the value using the given formatter.

impl Error for ModbusError

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<Error> for ModbusError
