Enum OpticalError 

pub enum OpticalError {
    InvalidLedPwm,
    InvalidIntegrationTime,
    GestureDetectionDisabled,
    Port {
        source: PortError,
    },
}

Errors that can occur when interacting with an optical sensor.

Variants

InvalidLedPwm

Invalid LED PWM value, must be between 0 and 100.

InvalidIntegrationTime

Integration time must be between 3 and 712 milliseconds.

See https://www.vexforum.com/t/v5-optical-sensor-refresh-rate/109632/9 for more information.

GestureDetectionDisabled

Gesture detection is not enabled for this sensor.

Port

Generic port related error.

Fields

source: PortError

The source of the error

Trait Implementations

impl Debug for OpticalError

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

Formats the value using the given formatter.

impl Display for OpticalError

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

Formats the value using the given formatter.

impl Error for OpticalError

where Self: 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 OpticalError

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 From<PortError> for OpticalError

fn from(error: PortError) -> Self

Converts to this type from the input type.

impl FromErrno for OpticalError

fn from_errno(num: i32) -> Option<Self>

Consume the current errno and, if it contains a known error, returns Self.
