}

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

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

Fields of WrongDatatype

expected: Datatype

The datatype expected by the method call.

actual: Datatype

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

WrongFormat

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

Fields of WrongFormat

format: String

The format string of the property.

ParseFailed

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

Fields of ParseFailed

value: String

The string value of the property.

datatype: Datatype

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

Trait Implementations

impl Clone for ValueError

pub fn clone(&self) -> ValueError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueError

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

Formats the value using the given formatter.

impl Display for ValueError

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

Formats the value using the given formatter.

impl Eq for ValueError

impl Error for ValueError

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

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

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

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

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

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<ValueError> for ValueError

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

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

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

This method tests for !=.
