Enum CommandError 

pub enum CommandError {
    Unsupported,
    UnknownTarget,
    InvalidAction,
    UnknownSensor,
}

Why a command could not be carried out. The code is a stable, language-neutral string the page localizes.

Variants

Unsupported

The source does not handle this kind of command.

UnknownTarget

No actuator or target matches the command.

InvalidAction

The target exists but does not accept the requested action.

UnknownSensor

The sensor being added is not one this device supports, so it was not added. A real device only accepts the sensor types it can actually bind a driver to.

Implementations

impl CommandError

pub fn code(self) -> &'static str

Returns the stable error code for this failure.

Returns

A dotted, language-neutral code such as "command.unknown_target".

Trait Implementations

impl Clone for CommandError

fn clone(&self) -> CommandError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CommandError

impl Debug for CommandError

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

Formats the value using the given formatter.

impl Eq for CommandError

impl PartialEq for CommandError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
