Struct UploadState 

pub struct UploadState {
    pub pending_payment: Option<PaymentAttempt>,
    /* private fields */
}

Prepared plans and confirmed proofs keyed by content address. Checkpoints contain no file bytes or wallet secrets.

Fields

pending_payment: Option<PaymentAttempt>

Submission journal; an unresolved attempt must be reconciled before another payment.

Implementations

impl UploadState

pub fn from_proofs(proofs: HashMap<XorName, Vec<u8>>) -> Self

Import the same per-content proofs used by native disk receipts.

pub fn retained_plan( &self, address: &XorName, size: u64, now: SystemTime, ) -> Option<ChunkPaymentPlan>

Reuse a previously prepared plan after a wallet callback was interrupted. Paid records are re-discovered so current storage targets replace stale ones.

pub fn prepare(&mut self, plan: ChunkPaymentPlan)

Retain a verified plan before invoking an external wallet.

pub fn is_paid(&self, address: &XorName, now: SystemTime) -> bool

Whether a confirmed, safely fresh proof already covers this record.

pub fn confirm( &mut self, addresses: &[XorName], transactions: &HashMap<QuoteHash, TxHash>, now: SystemTime, ) -> Result<()>

Bind a confirmed payment to all pending plans, before loading or storing bytes. Missing transactions fail atomically, preserving the prepared plans for recovery.

pub fn reuse_prepared( &self, prepared: &PreparedChunk, now: SystemTime, ) -> Option<PaidChunk>

Attach an existing proof to refreshed native or browser PUT targets.

pub fn checkpoint(&self) -> Result<Vec<u8>>

Serialize a local recovery checkpoint. Treat it like a native payment receipt.

pub fn restore(bytes: &[u8]) -> Result<Self>

Restore a local checkpoint, validating payment amounts and signed quote identities.
