A QPACK dynamic-table capacity, insertion, eviction, or index-resolution failure.

Variants

CapacityExceedsStorage

The requested capacity exceeds the supplied storage’s physical capacity.

Fields

requested: usize

The requested RFC dynamic-table capacity.

capacity: usize

The greatest RFC dynamic-table capacity the supplied stores can support.

EntrySizeOverflow

The RFC entry-size calculation overflowed usize.

EntryLargerThanCapacity

The entry cannot fit within the current dynamic-table capacity.

Fields

entry_size: usize

The calculated RFC entry size.

capacity: usize

The current RFC dynamic-table capacity.

InsertCountOverflow

A successful insertion would overflow the absolute insert count.

EvictionBlocked

An eviction required by an operation was rejected by the caller’s policy.

Fields

absolute_index: u64

The zero-based absolute index of the first entry whose eviction was rejected.

EncoderRelativeIndexUnderflow

An encoder-relative index exceeded the current insert count.

Fields

insert_count: u64

The current insert count.

index: u64

The requested encoder-relative index.

FieldRelativeIndexUnderflow

A field-relative index exceeded its base.

Fields

base: u64

The field section’s base.

index: u64

The requested field-relative index.

PostBaseIndexOverflow

A post-base index overflowed its base.

Fields

base: u64

The field section’s base.

index: u64

The requested post-base index.

FutureAbsoluteIndex

An absolute index has not yet been inserted.

Fields

requested: u64

The requested zero-based absolute index.

insert_count: u64

The current insert count.

EvictedAbsoluteIndex

An absolute index was evicted from the active table.

Fields

requested: u64

The requested zero-based absolute index.

oldest_available: u64

The oldest zero-based absolute index still available.

ReferenceAtOrAfterRequiredInsertCount

A field-line reference is at or after its Required Insert Count.

Fields

requested: u64

The requested zero-based absolute index.

required_insert_count: u64

The field section’s Required Insert Count.
