What can go wrong sealing, opening, locking or unlocking.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Malformed

The bytes are not a blob of the expected kind: too short, too long, or with another first byte.

Fields

expected: &'static str

What the bytes were read as.

reason: &'static str

What is wrong with them.

NewerFormat

The blob is of a format version this release does not know - written by a newer one.

Fields

kind: &'static str

What the bytes were read as.

found: u8

The version they carry.

WrongKey

The blob was sealed under another key; it names that key.

Fields

expected: KeyId

The key the blob was opened with.

found: KeyId

The key the blob says it was sealed under.

Inauthentic

The blob does not open under this key and this context: it was sealed for another context, or changed after sealing. The two cannot be told apart, and this error does not try.

WrongPassphrase

The lock does not open with this passphrase: the passphrase is wrong, the context is another one, or the lock was changed. Indistinguishable on purpose.

Parameters(String)

Argon2id parameters outside what this release accepts.

Random

The operating system could not supply random bytes.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
