Variants

BufferTooShort

Input buffer is too short for a complete header.

Fields

needed: usize

got: usize

BadMagic([u8; 4])

Magic bytes do not match.

VersionMismatch

Protocol version mismatch.

Fields

expected: u8

got: u8

PayloadTruncated

Payload length in header exceeds remaining buffer.

Fields

declared: usize

available: usize

PayloadTooLarge(usize)

Payload exceeds the maximum allowed size.

UnknownPacketKind(u16)

Unknown packet kind discriminant.

InvalidCompression(u8)

Unknown compression tag.

ReplayDetected

Packet was identified as a replay attack.

Fields

sequence: u32

EncodeError(String)

Generic encode error with a message.

Trait Implementations

impl Clone for ProtocolError

fn clone(&self) -> ProtocolError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Error for ProtocolError

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ProtocolError

fn eq(&self, other: &ProtocolError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
