Enum SensorError 

pub enum SensorError {
    Crc,
    Invalid,
    Identity,
}

What can go wrong turning a part’s raw bytes into a reading.

Most of these drivers only ever decode well-formed register values and so cannot fail, but parts that carry their own integrity check report a mismatch here so the caller re-reads rather than trusting corrupted data.

Variants

Crc

A device’s own checksum did not match the bytes it covered, so the read was corrupted on the bus and must be repeated. Returned, for example, when a DS18B20 scratchpad’s CRC byte disagrees with the data bytes.

Invalid

A register field holds a code the datasheet leaves undefined, so the value cannot have come from a correctly working part. Returned, for example, when an HDC1080 configuration register carries the unassigned humidity-resolution code.

Identity

A device’s identification registers did not carry the values its datasheet fixes, so a different part, or nothing at all, answered at that address and its readings must not be trusted. Returned, for example, when an INA226’s manufacturer or die ID register reads something other than TI’s 0x5449 and 0x226.

Trait Implementations

impl Clone for SensorError

fn clone(&self) -> SensorError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SensorError

impl Debug for SensorError

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

Formats the value using the given formatter.

impl Display for SensorError

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

Formats the value using the given formatter.

impl Eq for SensorError

impl Error for SensorError

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 PartialEq for SensorError

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