Enum embedded_hal_async::i2c::ErrorKind

#[non_exhaustive]
pub enum ErrorKind {
    Bus,
    ArbitrationLoss,
    NoAcknowledge(NoAcknowledgeSource),
    Overrun,
    Other,
}

I2C error kind.

This represents a common set of I2C operation errors. HAL implementations are free to define more specific or additional error types. However, by providing a mapping to these common I2C errors, generic code can still react to them.

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.

Bus

Bus error occurred. e.g. A START or a STOP condition is detected and is not located after a multiple of 9 SCL clock pulses.

ArbitrationLoss

The arbitration was lost, e.g. electrical problems with the clock signal.

NoAcknowledge(NoAcknowledgeSource)

A bus operation was not acknowledged, e.g. due to the addressed device not being available on the bus or the device not being ready to process requests at the moment.

Overrun

The peripheral receive buffer was overrun.

Other

A different error occurred. The original error may contain more information.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Error for ErrorKind

fn kind(&self) -> ErrorKind

Convert error to a generic I2C error kind.

impl Hash for ErrorKind

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

where __H: Hasher,

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 Ord for ErrorKind

fn cmp(&self, other: &ErrorKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ErrorKind

fn eq(&self, other: &ErrorKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ErrorKind

fn partial_cmp(&self, other: &ErrorKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
