Enum embedded_hal::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

Tuple Fields of NoAcknowledge

0: NoAcknowledgeSource

Overrun

The peripheral receive buffer was overrun

Other

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