Enum Error

#[non_exhaustive]
pub enum Error {
    FifoExceeded,
    AcknowledgeCheckFailed(AcknowledgeCheckFailedReason),
    Timeout,
    ArbitrationLost,
    ExecutionIncomplete,
    CommandNumberExceeded,
    ZeroLengthInvalid,

I2C-specific transmission errors

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

FifoExceeded

The transmission exceeded the FIFO size.

AcknowledgeCheckFailed(AcknowledgeCheckFailedReason)

The acknowledgment check failed.

Timeout

A timeout occurred during transmission.

ArbitrationLost

The arbitration for the bus was lost.

ExecutionIncomplete

The execution of the I2C command was incomplete.

CommandNumberExceeded

The number of commands issued exceeded the limit.

ZeroLengthInvalid

Zero length read or write operation.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error for Error

fn kind(&self) -> ErrorKind

Convert error to a generic I2C error kind.

impl Format for Error

where AcknowledgeCheckFailedReason: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given [Hasher].

impl PartialEq for Error

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