Struct AccountRound 

pub struct AccountRound { /* private fields */ }

One round’s state. Every field is private: a round moves only through AccountRound::apply and AccountRound::repaired.

Implementations

impl AccountRound

pub fn start( roster: Roster, usable: BTreeSet<ServerLabel>, cap: Retries, held: Option<ServerLabel>, ) -> Result<AccountRound, RoundEnd>

Opens a round before its first send, and counts that send. The account held - the Session’s binding on the model path, absent for web_search - opens the round while it is listed and redeemable; otherwise the first redeemable account in roster order does.

Errors

RoundEnd::Exhausted when no listed account is redeemable: the round sends nothing.

pub fn current(&self) -> Option<&ServerLabel>

The account the next send goes out on; None for a single-account roster, which names none.

pub fn next(&self, failure: &AxError) -> AccountStep

What to do after failure, read from its retry and its account disposition alone (D54).

pub fn apply(self, step: &AccountStep) -> AccountRound

The round after the driver carried out step. Stop changes nothing. The counts saturate rather than wrap: a single-account round under UntilHalted resends until a Halt, and a count that wrapped would read as a fresh account’s spare sends.

pub fn admits_repair(&self) -> bool

Whether the repair stage may send the request again through the blocking door. With several accounts that send is one more on the current account, so it needs the account’s spare sends and the person’s ceiling; a single-account roster is let through as before.

pub fn repaired(self) -> AccountRound

The round after the repair stage sent again: one more send on the current account with several accounts, uncounted with one.
