Enum EnvelopeError 

pub enum EnvelopeError {
    Version(u8),
    Truncated(usize),
    Decrypt,
    NonContributory,
    BadSignature,
    Hex(FromHexError),
    KeyLength(usize),
}

Errors from envelope operations.

Variants

Version(u8)

Blob’s leading version byte is not one we understand.

Truncated(usize)

Blob is structurally too short for its layout.

Decrypt

AEAD decryption failed (wrong key, tampered ciphertext, or wrong AAD context).

NonContributory

The ECDH shared secret was the all-zero point (non-contributory peer key — a small-order or identity public key).

BadSignature

The embedded Ed25519 signature did not verify against the sender key and context.

Hex(FromHexError)

Hex decoding of a revealed message key failed.

KeyLength(usize)

A revealed message key had the wrong length.

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, __formatter: &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.

impl From<FromHexError> for EnvelopeError

fn from(source: FromHexError) -> Self

Converts to this type from the input type.
