Enum I2cError

#[non_exhaustive]
pub enum I2cError {
    Bus,
    ArbitrationLoss,
    NACK,
    Overrun,

    PacketErrorChecking,
    Timeout,
    Alert,
    Impl(ImplError),
}

An I2C specific error.

This error type contains errors specific to I2C peripherals. Also it has an Impl kind to pass through implementation specific errors occurring while trying to use an I2C peripheral.

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

An unspecific bus error occured

ArbitrationLoss

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

NACK

A bus operation received a NACK, e.g. due to the addressed device not being available on the bus or device not being ready to process any requests at the moment

Overrun

The peripheral receive buffer was overrun

Underrun

The peripheral send buffer ran out of data

PacketErrorChecking

SMBus Error checking byte mismatch

Timeout

SMBus Timeout error

Alert

SMBus Alert received

Impl(ImplError)

Implementation specific error (shared across all peripheral specific error kinds)
