Enum EnvelopeError 

pub enum EnvelopeError {
    FrameCount,
    HeaderLength,
    Magic,
    Major(u8),
    Opcode(u8),
    Flags,
    Length,
    Limit,
    ZeroIdentity,
    Correlation,
    Session,
    Handshake,
}

Structural native envelope rejection, without interpreting command semantics.

Variants

FrameCount

Exactly three frames are required, including present empty frames.

HeaderLength

Header is not exactly 64 bytes.

Magic

Magic does not identify Ozzy.

Major(u8)

No implicit legacy fallback or future-major interpretation.

Opcode(u8)

Unallocated command number.

Flags

Flags other than the response bit are reserved.

Length

Claimed sizes differ from actual frames or exceed the wire integer width.

Limit

Frame exceeds the directional receiver’s configured bound.

ZeroIdentity

Mandatory sender or explicitly supplied optional ID is zero.

Correlation

A response cannot be uncorrelated.

Session

Only HELLO can omit the link session.

Handshake

Invalid HELLO/WELCOME direction, correlation, session, or payload.

Trait Implementations

impl Clone for EnvelopeError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EnvelopeError

impl Debug for EnvelopeError

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

Formats the value using the given formatter.

impl Display for EnvelopeError

impl Eq for EnvelopeError

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.
