Enum UploadBackpressure 

pub enum UploadBackpressure {
    InvalidConfiguration,

}

Why an upload reservation or lifecycle transition could not proceed.

Variants

InvalidConfiguration

Configuration must provide non-zero capacities and power-of-two alignment.

EmptyUpload

Empty uploads are rejected.

EpochBudget

The configured per-epoch payload budget was exhausted.

InFlightBudget

Submitted work reached its fence-protected byte budget.

RingFull

Staging bytes remain occupied by older work.

TicketCapacity

All ticket records are in use.

SizeOverflow

Arithmetic could not represent the reservation.

InvalidTicket

The ticket is stale or in the wrong lifecycle state.
