Enum RowError 

#[non_exhaustive]
pub enum RowError {
    Remote(RemoteError),
    NoValue,
    Other(String),
}

Why one property of a read has no value. Structured, so a front end can report the device’s error class and code as data, not only as text.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Remote(RemoteError)

The device answered this property with an error, a reject or an abort.

NoValue

The device’s answer for this property held neither a value nor an error.

Other(String)

Any other failure of this property’s read, as text.

Implementations

impl RowError

pub fn class_code(&self) -> Option<(ErrorClass, ErrorCode)>

The device’s error class and code, when it answered with an error.

Trait Implementations

impl Clone for RowError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowError

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

Formats the value using the given formatter.

impl Display for RowError

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

An error as CLASS:CODE (PROPERTY:UNKNOWN_PROPERTY), the form the TUI shows; a reject or abort, or any other failure, as its own text.

impl Eq for RowError

impl Error for RowError

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 RowError

fn from(error: Error) -> Self

The device’s error, reject or abort as RowError::Remote, with a structured Error PDU reduced to its class and code; anything else as text.

impl PartialEq for RowError

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

Equality operator ==.

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

Inequality operator !=.
