Struct SharedCostPermit 

pub struct SharedCostPermit<'state, 'request, 'fingerprint> { /* private fields */ }

Shared atomic price-bounded authority.

Every clone references the same caller-owned atomic state. Cloning never creates new budget or an independent recovery generation.

Implementations

impl<'state, 'request, 'fingerprint> SharedCostPermit<'state, 'request, 'fingerprint>

pub fn new( state: &'state mut SharedPermitState, subject: PlanSubject<'request, 'fingerprint>, now: PermitTimestamp, ) -> Result<Self, ExecutionPermitError>

Exclusively binds fresh shared state to one confirmed plan.

pub fn state(&self) -> PermitState

Returns the shared lifecycle state.

pub fn begin( &self, now: PermitTimestamp, ) -> Result<PermitAttempt<'_, 'request, 'fingerprint>, ExecutionPermitError>

Atomically starts one attempt for the bound plan.

pub fn begin_for( &self, candidate: PlanSubject<'_, '_>, now: PermitTimestamp, ) -> Result<PermitAttempt<'_, 'request, 'fingerprint>, ExecutionPermitError>

Starts only if the candidate fingerprint matches the bound plan.

pub fn recover_not_sent( &self, token: RecoveryToken, now: PermitTimestamp, ) -> Result<(), ExecutionPermitError>

Atomically recovers a generation-matched NotSent attempt.

pub fn reconcile_not_applied( &self, token: ReconciliationToken, candidate: PlanSubject<'_, '_>, idempotency: PermitIdempotencyKey<'_>, now: PermitTimestamp, ) -> Result<(), ExecutionPermitError>

Rearms after caller-performed operation-specific reconciliation.

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SharedCostPermit<'_, '_, '_>

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
