Enum PexErrorCode 

#[repr(u16)]
pub enum PexErrorCode {
    BadMessage = 1,
    UnsupportedVersion = 2,
    RateViolation = 3,
    Oversized = 4,
    NetworkMismatch = 5,
    ProtocolViolation = 6,
}

The advisory pex_error code table (SPEC §4.5). pex_error is best-effort and never requires a reply; a receiver sends it alongside discarding a bad message / muting a direction.

Variants

BadMessage = 1

1 — the message was not valid PEX JSON, or violated a structural MUST (e.g. a peer_id appearing in both added and dropped).

UnsupportedVersion = 2

2 — the handshake version is not supported by the receiver.

RateViolation = 3

3 — data messages arrived faster than the enforced minimum interval (SPEC §6.4).

Oversized = 4

4 — a frame exceeded PEX_MAX_FRAME, or a list exceeded its cap (SPEC §7).

NetworkMismatch = 5

5 — the handshake network_id differs from the receiver’s.

ProtocolViolation = 6

6 — a state-machine violation (SPEC §5.3): data before handshake, a second snapshot, or a delta before the snapshot.

Implementations

impl PexErrorCode

pub fn as_u16(self) -> u16

The numeric code as it appears on the wire.

pub fn message(self) -> &'static str

A short, stable human-readable message for the pex_error.message field.

pub fn is_strike(self) -> bool

Whether this code represents peer misbehavior that counts a strike toward muting (SPEC §11.2): bad-message (1), rate (3), oversize (4), and protocol (6). Version (2) and network (5) mismatch mute the direction immediately but are NOT misbehavior — the peer is simply on a different version/network, and the underlying connection MUST NOT be torn down for that reason alone (SPEC §5.2).
