The error type for the ev3dev_rs crate

Variants

SensorNotFound

Unable to find a sensor.

Fields

port: SensorPort

The port the sensor was supposed to be on.

expected_sensor_type: SensorType

The expected sensor type.

MotorNotFound

Unable to find a motor.

Fields

port: MotorPort

The port the motor was supposed to be on.

FileNotFound

An internal error

Fields

path: PathBuf

The name of the expected file

InvalidPath

An internal error

IncorrectSensorType

Found the incorrect sensor

Fields

expected: SensorType

The type of the expected sensor.

found: SensorType

The type of the found sensor

ParseStr

Failed to parse a string into an enum variant.

Fields

input: String

The string that was unable to be parsed.

to: String

The name of the enum

PermissionDenied

An internal error

Fields

required_permission: FileMode

The permission that was expected

InvalidStringBytes

Failed to read the contents of a sysfs file to a string.

ReadAttributeFailure

Unable to read a motor or sensor attribute.

Fields

filename: PathBuf

The name of the file that failed to read

os_error: Error

The raw OS error.

WriteAttributeFailure

Failed to write to an attribute of a sensor or motor.

Fields

filename: PathBuf

The name of the file that we failed to write to.

value: String

The value that we tried to write.

os_error: Error

The raw OS error.

ParseInt

Failed to parse an integer

Fields

err: ParseIntError

The raw error

ParseFloat

Failed to parse a floating point number.

Fields

err: ParseFloatError

The raw error

InvalidValue

Failed to read a string into an enum variant.

Fields

func: String

The function that tried to read the value.

value: String

The value.

NoSensorProvided

No sensor was provided to something that needed it.

This was most likely caused by a DriveBase not being provided a GyroSensor.

Trait Implementations

impl Debug for Ev3Error

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

Formats the value using the given formatter.

impl Display for Ev3Error

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

Formats the value using the given formatter.

impl Error for Ev3Error

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<ParseFloatError> for Ev3Error

fn from(err: ParseFloatError) -> Self

Converts to this type from the input type.

impl From<ParseIntError> for Ev3Error

fn from(err: ParseIntError) -> Self

Converts to this type from the input type.
