}

An error encountered while parsing the value or format of a property.

Variants

Unknown

The value of the property or attribute is not yet known, or not set by the device.

WrongDatatype

Fields

expected: Datatype

The datatype expected by the method call.

actual: Datatype

The actual datatype of the property, as sent by the device.

The method call expected the property to have a particular datatype, but the datatype sent by the device was something different.

WrongFormat

Fields

format: String

The format string of the property.

The format of the property couldn’t be parsed or didn’t match what was expected by the method call.

ParseFailed

Fields

value: String

The string value of the property.

datatype: Datatype

The datatype as which the value was attempted to be parsed.

The value of the property couldn’t be parsed as the expected type.

Trait Implementations

impl Clone for ValueError

fn clone(&self) -> ValueError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ValueError

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

Formats the value using the given formatter.

impl Display for ValueError

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

Formats the value using the given formatter.

impl Error for ValueError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl PartialEq<ValueError> for ValueError

fn eq(&self, other: &ValueError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ValueError) -> bool

This method tests for !=.
