Errors when sending/receiving p2p messages. These should result in kicking the peer.

Variants

Io(Error)

I/O error.

Rlp(Error)

RLP encoding/decoding error.

Snap(Error)

Error in compression/decompression using Snappy.

HandshakeError(P2PHandshakeError)

Error during the P2P handshake.

MessageTooBig

Message size exceeds maximum length error.

Fields

message_size: usize

The actual size of the message received.

max_size: usize

The maximum allowed size for the message.

SubprotocolMessageTooBig

A subprotocol message exceeds the limit declared by its local handler.

Fields

capability: Capability

The negotiated capability whose limit was exceeded.

message_size: usize

The frame size, including the capability-local message ID.

max_size: usize

The maximum frame size declared by the protocol handler.

SubprotocolInboundBufferFull

A subprotocol’s bounded inbound queue has no remaining capacity.

Fields

capability: Capability

The negotiated capability whose queue is full.

UnknownSubprotocolMessageId(u8)

An incoming message ID is outside all negotiated subprotocol ranges.

UnknownReservedMessageId(u8)

Unknown reserved P2P message ID error.

EmptyProtocolMessage

Empty protocol message received error.

InvalidPingPongPayload(u8)

Ping or Pong payload is not an RLP empty list.

TooManyPings

Incoming ping rate limit exceeded.

PingerError(PingerError)

Error related to the Pinger.

PingTimeout

Ping timeout error.

ParseSharedCapability(SharedCapabilityError)

Error parsing shared capabilities.

CapabilityNotShared

Capability not supported on the stream to this peer.

MismatchedProtocolVersion(GotExpected<ProtocolVersion>)

Mismatched protocol version error.

SendBufferFull

Too many messages buffered before sending.

Disconnected(DisconnectReason)

Disconnected error.

UnknownDisconnectReason(UnknownDisconnectReason)

Unknown disconnect reason error.

Implementations

impl P2PStreamError

pub const fn as_disconnected(&self) -> Option<DisconnectReason>

Returns the DisconnectReason if it is the Disconnected variant.

Trait Implementations

impl Debug for P2PStreamError

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

Formats the value using the given formatter.

impl Display for P2PStreamError

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

Formats the value using the given formatter.

impl Error for P2PStreamError

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 #99301)

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
