Enum QpackError 

pub enum QpackError {
    DecompressionFailed,
    EncoderStream,
    DecoderStream,
}

Available on crate feature h3 only.

Errors raised while QPACK state is inconsistent or a representation is malformed.

DecompressionFailed is produced by field section decoding, the other two by processing of the peer’s respective QPACK stream. All three are fatal for the connection: there is no way to resynchronize.

Variants

DecompressionFailed

QPACK_DECOMPRESSION_FAILED (0x0200): a field section could not be decoded, or references an entry that is evicted or out of range, or exceeds the advertised SETTINGS_MAX_FIELD_SECTION_SIZE.

EncoderStream

QPACK_ENCODER_STREAM_ERROR (0x0201): an encoder stream instruction was malformed or violated table constraints.

DecoderStream

QPACK_DECODER_STREAM_ERROR (0x0202): a decoder stream instruction was malformed. Kept so QpackError::code mirrors the full error family; this implementation only emits decoder stream instructions, it never parses them, so the variant is never constructed.

Implementations

impl QpackError

pub fn code(self) -> u16

The HTTP/3 CONNECTION_CLOSE error code (RFC 9204 Section 6).

Consumed by the HTTP/3 layer and by the error-module tests that pin the 0x02xx family against the 0x01xx HTTP/3 family.
