Enum OpenError 

pub enum OpenError {
    Decode(DecodeError),
    RecipientKeyMismatch,
    PartyMismatch,
    OpenFailed,
    Provider {
        message: String,
    },
}

Why opening (decrypting) a message failed.

Authentication failures are deliberately opaque: a wrong key, tampered ciphertext, mismatched external AAD, and a low-order ephemeral all surface as the single OpenError::OpenFailed arm (no oracle).

Variants

Decode(DecodeError)

Strict decode rejected the message.

RecipientKeyMismatch

The message is addressed to a different recipient key id.

PartyMismatch

The KDF party identities on the wire do not match the pinned expectation.

OpenFailed

AEAD authentication failed: wrong key, tampered ciphertext or headers, mismatched external AAD, or a degenerate (low-order) ephemeral. Opaque on purpose.

Provider

The backing provider (for example the broker unseal RPC) failed. The message is diagnostic transport/provider detail, never key material.

Fields

message: String

Human-readable provider failure detail.

Trait Implementations

impl Clone for OpenError

fn clone(&self) -> OpenError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpenError

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

Formats the value using the given formatter.

impl Display for OpenError

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

Formats the value using the given formatter.

impl Eq for OpenError

impl Error for OpenError

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.

impl From<DecodeError> for OpenError

fn from(e: DecodeError) -> Self

Converts to this type from the input type.

impl PartialEq for OpenError

fn eq(&self, other: &OpenError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
