Enum EnvelopeSealError 

pub enum EnvelopeSealError {
    Absent,
    WireUndeclared(String),
    Refused(AphError),
}

Why an envelope-level unseal can fail — three DIFFERENT kinds of failure with three different repairs, kept as distinct as the codes that carry two of them.

Variants

Absent

The envelope carries no sealedPayload. Not a refusal: an unsealed envelope is an ordinary envelope, and the caller decides whether it expected one.

WireUndeclared(String)

The wire-version rule refused: sealedPayload on an aphVersion that does not declare it. Strict-parse CLASS — a plain message below the protocol’s code vocabulary, per the same reasoning as an unrecognized closed-set value.

Refused(AphError)

A protocol refusal with its 0.2 code: APH_E021 (the seal addressed to this verifier did not open) or APH_E022 (unknown suite). Per RFC 0008 §4 the caller MUST refuse the ENVELOPE.

Trait Implementations

impl Debug for EnvelopeSealError

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

Formats the value using the given formatter.

impl Display for EnvelopeSealError

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

Formats the value using the given formatter.

impl Error for EnvelopeSealError

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>)
