Enum CloseReason

    ZeroLength,
    OverCeiling(usize),

Why a reader closed its stream.

Every variant is terminal: a closed reader delivers nothing more, and the host closes the socket. None of them is a peer’s fault the host should report upward; a stream that never proved a peer was never announced, so there is nothing to report lost.

Variants

ZeroLength

A prefix of zero. No encoding produces an empty message.

OverCeiling(usize)

A prefix above PEER_STREAM_MAX_FRAME_BYTES, refused before the body.

PreambleUnderFloor(usize)

A preamble prefix under PEER_STREAM_PREAMBLE_FLOOR, refused before the body: a key and most of a signature cannot verify.

PreambleRejected

The first body did not verify as an identity assertion. A well-formed message arriving first lands here too: position decides what a body is, and a message is not a preamble.

AddressMismatch

The preamble verified, but the stream was opened toward a different address (a peer-list entry, an invite, a discovery record’s addr). The comparison is exact, never case-folded.

Fields

expected: String

The address the stream was opened toward.

derived: String

The address the preamble proved.

Trait Implementations

impl Eq for CloseReason

impl Error for CloseReason

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.
