Errors that can occur during QUIC packet parsing and decryption.

Variants

BufferTooShort

The input buffer is shorter than required.

Fields

need: usize

Minimum number of bytes required.

have: usize

Actual number of bytes available.

NotLongHeader

The packet does not have the long header form bit set.

InvalidFixedBit

The fixed bit (bit 6) of the first byte is not set to 1.

NotInitialPacket(u8)

The packet is a long header but not an Initial packet.

InvalidCidLength(u8)

A connection ID length field exceeds the protocol maximum of 20 bytes.

UnsupportedVersion(u32)

The QUIC version is not supported for decryption.

DecryptionFailed(String)

AEAD decryption or key derivation failed.

TruncatedFrame

A CRYPTO frame was truncated before its declared length.

Fields

offset: u64

The byte offset within the decrypted payload where truncation occurred.

InvalidVarint

The variable-length integer encoding is malformed.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
