Variants

ComputeSignature

An error occurred while computing the cryptographic signature used for decryption.

NonceRequest

Sending the request to gather the metadata encryption nonce failed.

NonceResponse(ResponseError)

The server responded with an error while fetching the metadata encryption nonce.

Nonce(NonceError)

Couldn't parse the metadata encryption nonce.

Malformed

The received metadata is malformed, and couldn't be decoded or interpreted.

Decrypt

Failed to decrypt the received metadata.

Trait Implementations

impl From<MetaError> for Error

fn from(err: MetaError) -> Error

Performs the conversion.

impl Fail for MetaError

fn cause(&self) -> Option<&Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where     D: Display + Send + Sync + 'static,

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

Important traits for Causes<'f>

impl<'f> Iterator for Causes<'f> type Item = &'f (Fail + 'static);

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.

impl Display for MetaError

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

Formats the value using the given formatter.

impl Debug for MetaError

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

Formats the value using the given formatter.
