Failure to encode one QPACK field section.

Variants

ReferenceCountOverflow

Counting dynamic-reference occurrences overflowed usize.

ReferenceScratchTooShort

The caller supplied too little reference scratch.

Fields

required: usize

Required number of reference slots.

available: usize

Available reference slots.

FieldPlanScratchTooShort

The caller supplied too little retained field-plan scratch.

Fields

required: usize

Required number of plan slots.

available: usize

Available plan slots.

Plan(QpackFieldSectionPlanError)

One semantic field plan is invalid.

RequiredInsertCountOverflow

Adding one to the largest dynamic absolute index overflowed u64.

Fields

absolute_index: u64

Largest zero-based absolute index.

BaseExceedsInsertCount

The explicit Base is greater than the dynamic table insert count.

Fields

base: u64

Requested Base.

insert_count: u64

Current dynamic-table insert count.

RequiredInsertCountEncoding(QpackFieldSectionContextError)

Required Insert Count context encoding failed.

PrefixPlanning(QpackFieldSectionPrefixBuildError)

Prefix wire planning failed.

OutputLengthOverflow

Summing the complete output length overflowed usize.

DestinationTooShort

The destination is too short for the complete field section.

Fields

required: usize

Required output bytes.

available: usize

Available output bytes.

EncoderStateReservation(QpackEncoderStateError)

Encoder accounting could not reserve the dynamic references.

Implementations

impl QpackFieldSectionEncodeError

pub const fn is_provisioning_error(self) -> bool
