Encompasses the different errors directly returned by this crate.

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.

InvalidArgument(&'static str)

An argument was invalid.

It describes why the argument is invalid.

Bug(Bug)

An internal bug was discovered.

Seal(SealError)

An AEAD seal failure.

Open(OpenError)

An AEAD open failure.

Ecdh(EcdhError)

An ECDH failure.

Hpke(HpkeError)

An HPKE failure.

Kdf(KdfError)

A KDF failure.

Kem(KemError)

A KEM failure.

Mac(MacError)

A MAC failure.

Signer(SignerError)

A digital signature failure.

Import(ImportError)

An import failure.

Export(ExportError)

An export failure.

Wrap(WrapError)

A key wrapping failure.

Unwrap(UnwrapError)

A key unwrapping failure.

Id(IdError)

An identifier failure.

Pk(PkError)

A public key failure.

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 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: &Error) -> 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.
