Enum kernel::hil::i2c::Error

pub enum Error {
    AddressNak,
    DataNak,
    ArbitrationLost,
    Overrun,
    NotSupported,
    Busy,
}

The type of error encountered during I2C communication.

Variants

AddressNak

The slave did not acknowledge the chip address. Most likely the address is incorrect or the slave is not properly connected.

DataNak

The data was not acknowledged by the slave.

ArbitrationLost

Arbitration lost, meaning the state of the data line does not correspond to the data driven onto it. This can happen, for example, when a higher-priority transmission is in progress by a different master.

Overrun

A start condition was received before received data has been read from the receive register.

NotSupported

The requested operation wasn’t supported.

Busy

The underlying device has another request in progress

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, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Error> for ErrorCode

fn from(val: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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