Type Alias PreparedTileBatchError 

pub type PreparedTileBatchError = BatchInfrastructureError;

Allocation, scheduling, or collection failure for a prepared JPEG batch.

Prepared batches retain codec failures independently in their returned per-tile result vector, so only infrastructure failures use this outer type.

Variants

EmptyBatchPlan

An internal planning boundary was invoked without any submitted jobs.

AllocationTooLarge

Batch-owned metadata would exceed the operation’s host-memory budget.

Fields

what: &'static str

Name of the batch-owned allocation or live set.

requested: usize

Requested live byte count, saturated to usize::MAX on overflow.

cap: usize

Maximum permitted live byte count.

HostAllocationFailed

The host allocator rejected an otherwise cap-valid reservation.

Fields

what: &'static str

Name of the batch-owned allocation.

bytes: usize

Requested host byte count.

WorkerSpawnFailed

The host could not create a requested scoped worker.

Fields

worker: usize

Zero-based worker index in the planned batch.

WorkerPanicked

A worker unwound before completing its assigned jobs.

Fields

worker: usize

Zero-based worker index in the planned batch.

WorkerSlotMissing

Planned work referenced a worker slot that does not exist.

Fields

worker: usize

Missing zero-based worker slot.

available: usize

Number of worker slots available to the scheduler.

ParallelWorkerPanicked

A worker managed by a shared parallel runtime unwound.

SchedulerPoisoned

Shared batch state was poisoned by an earlier unwind.

ResultIndexOutOfBounds

A worker reported an index outside the submitted job range.

Fields

index: usize

Invalid worker-reported index.

job_count: usize

Number of submitted jobs.

DuplicateResult

More than one worker result claimed the same job index.

Fields

index: usize

Duplicated job index.

MissingResult

No worker result was produced for a submitted job.

Fields

index: usize

Missing job index.

ResultKindMismatch

Collector state contradicted a result kind it had just inspected.

Fields

index: usize

Job index whose result kind contradicted the inspected state.
