Enum Error 

#[non_exhaustive]
pub enum Error {
    Bus,
    ArbitrationLoss,
    Overrun,
    NoAcknowledge(NoAcknowledgeSource),
    Pec,
    SmbusTimeout,
    SmbusAlert,
}

An error the peripheral flagged in STAT0 (manual Table 17-3).

kind gives the portable classification.

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

A START or STOP arrived where the protocol allows none (BERR).

ArbitrationLoss

Another master won the bus; this one fell back to slave mode (LOSTARB).

Overrun

A byte was overwritten before being read, or needed before being written (OUERR). Slave mode only, with clock stretching disabled.

NoAcknowledge(NoAcknowledgeSource)

Nobody acknowledged (AERR) — the ordinary answer from an empty address, which is what bus scans rely on.

One flag covers both cases, so the source comes from the step that ran.

Pec

The received PEC does not match the one computed locally (PECERR).

SmbusTimeout

An SMBus transaction exceeded its timeout (SMBTO).

SmbusAlert

An SMBus device pulled the alert line (SMBALT).
