Enum ControllerError 

pub enum ControllerError {
    Offline,
    CompetitionControl,
    WriteBusy,
}

Available on crate feature devices only.

Errors that can occur when interacting with the controller.

Variants

Offline

The controller is not connected to the Brain.

CompetitionControl

Access to controller data is restricted by competition control.

When this error occurs, the requested data is not available outside of driver control mode.

WriteBusy

Attempted to write a buffer to the controller’s screen before the previous buffer was sent.

Trait Implementations

impl Clone for ControllerError

fn clone(&self) -> ControllerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ControllerError

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

Formats the value using the given formatter.

impl Display for ControllerError

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

Formats the value using the given formatter.

impl Error for ControllerError

where ControllerError: Debug + Display,

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

Returns the lower-level source of this error, if any.

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 ErrorCompat for ControllerError

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

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl PartialEq for ControllerError

fn eq(&self, other: &ControllerError) -> 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.
