Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CapsMismatch

Phase 1: no non-empty intersection between proposed upstream caps and this element’s supported caps.

NotConfigured

Element received a DataFrame before configure_pipeline succeeded.

FixationFailed

Phase 2: caller should retry Phase 1 with the proposal returned in ConfigureOutcome::ReFixate.

PoolExhausted

Buffer pool exhausted; transient, retry after upstream drain.

UnsupportedDomain

A MemoryDomain variant was handed to an element that cannot consume it.

AllocationConflict

Two branches of a fan-out (a tee’s diamond) proposed allocation parameters with no common memory domain, so there is no pool the shared producer can allocate that satisfies both. The negotiation fails loud rather than silently honouring one branch and copying for the other.

Hardware(HardwareError)

Backend-specific hardware or driver failure.

Shutdown

Pipeline is shutting down; element should drain and propagate Eos.

CopyBudget

A CopyPolicy enforced on the graph was violated: the negotiated pipeline performs more memory-domain frame copies (device<->host or cross-device transfers of a raw buffer) than the budget allows. Raised before any frame flows, so a pipeline that must stay zero-copy refuses to start rather than paying the copy at runtime. Inspect copy_plan for the offending transfers.

InputRefused

A fan-in element refused an input added at runtime (MultiInputElement::accepts_runtime_input): it has no pad for that source, so the add fails and the run continues on the inputs it already has.

ControlBinding

An animated property binding (M882) does not fit the element it was attached to: an unknown or non-animatable property name (raised at startup, before any frame flows), or a sampled value the element refused mid-run. The offending node and property are named on the log’s runtime category.

Timeout

No data reached an element within the time it was given: the watchdog transform’s timeout elapsed with the stream stalled.
