Enum PairingFailureReason 

pub enum PairingFailureReason {
    Timeout,
    Rejected,
    Cancelled,
    ClientOutdated,
    Error,
    Unknown(String),
}

Why a pairing attempt ended without linking the number. The set is closed, but a newer server may add a value: it decodes as PairingFailureReason::Unknown instead of failing, so treat it like PairingFailureReason::Error when is_known is false.

Variants

Timeout

Nobody read the QR or typed the code in time (the QR channel lasts about 160 s).

Rejected

WhatsApp refused the link.

Cancelled

disconnect or pause ended the attempt.

ClientOutdated

WhatsApp refuses the connector’s version.

Error

Any other failure.

Unknown(String)

A value this SDK version does not know.
