Enum ZkrSeedPoll 

pub enum ZkrSeedPoll {
    Bist,
    Wait,
    Es16(u16),
    Dead,
}

Result of polling the entropy source behind the Zkr extension’s seed CSR, corresponding to one of the specification’s OPST states

Variants

Bist

Built-in self-test is being performed (OPST=BIST).

If this is returned after some other state was previously observed, it signals a non-fatal, but noteworthy, self-test alarm.

Wait

A sufficient amount of entropy is not yet available (OPST=WAIT).

This is not an error condition and may be observed more often than Self::Es16, since physical entropy sources often have low bandwidth.

Es16(u16)

16 bits of randomness are available (OPST=ES16), guaranteed to meet the specification’s minimum entropy requirements regardless of implementation.

Dead

An unrecoverable self-test error has occurred (OPST=DEAD).

Once returned, all future polls are expected to also return Self::Dead.
