Errors from sealing or opening a Community message envelope.

Variants

Sign(String)

Encrypt(String)

Decrypt(String)

InnerParse(String)

BadVersion(Option<String>)

Outer v tag is absent or names a version we don’t speak.

KindMismatch

Fields

outer: u16

inner: u16

ChannelMismatch

Inner channel id ≠ the channel whose key decrypted this (cross-channel splice).

EpochMismatch

Inner epoch ≠ the epoch whose key decrypted this (cross-epoch splice/replay).

BadSignature

Inner author signature failed to verify.

MissingTag(&'static str)

DuplicateTag(&'static str)

A binding tag appears more than once — the inner event is ambiguous, so the wire form isn’t deterministic. Any channel-key holder can craft the inner event, so we reject rather than trust first-match.

NoHeldEpoch

The outer z pseudonym matches none of the member’s held epoch keys (an epoch we were never a recipient of, or a foreign channel). Not ours to read — dropped, not an error condition.

Trait Implementations

impl Debug for EnvelopeError

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

Formats the value using the given formatter.

impl Display for EnvelopeError

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

Formats the value using the given formatter.

impl Error for EnvelopeError

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.
