A failure while accounting for an encoder field section’s dynamic references.

Variants

RequiredInsertCountMismatch

The Required Insert Count does not match the supplied dynamic references.

Fields

required_insert_count: u64

The supplied Required Insert Count.

expected_required_insert_count: u64

The Required Insert Count implied by the references.

RequiredInsertCountOverflow

Adding one to the largest absolute reference overflowed u64.

Fields

absolute_index: u64

The largest supplied zero-based absolute index.

RequiredInsertCountExceedsInsertCount

The Required Insert Count is greater than the encoder’s insert count.

Fields

required_insert_count: u64

The supplied Required Insert Count.

encoder_insert_count: u64

The encoder’s current insert count.

SectionStorageExhausted

The caller supplied no remaining section metadata slots.

Fields

capacity: usize

The number of supplied section metadata slots.

ReferenceStorageTooShort

The caller supplied too few reference slots for all occurrences.

Fields

required: usize

The number of additional reference slots required.

available: usize

The number of remaining reference slots available.

BlockedStreamsLimitExceeded

Starting a field section would exceed the peer’s blocked-stream limit.

Fields

maximum: u64

The peer’s SETTINGS_QPACK_BLOCKED_STREAMS value.

Implementations

impl QpackEncoderStateError

pub const fn is_provisioning_error(self) -> bool

Returns whether this failure is caused by insufficient caller-owned storage.

pub const fn is_blocked_streams_limit_error(self) -> bool

Returns whether this failure requires choosing a nonblocking representation.
