A set of errors that can occur in the IMAP client

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.

Io(IoError)

An io::Error that occurred while trying to read or write to a network stream.

TlsHandshake(TlsHandshakeError<TcpStream>)

An error from the native_tls library during the TLS handshake.

Tls(TlsError)

An error from the native_tls library while managing the socket.

Bad(Bad)

A BAD response from the IMAP server.

No(No)

A NO response from the IMAP server.

Bye(Bye)

A BYE response from the IMAP server.

ConnectionLost

The connection was terminated unexpectedly.

Parse(ParseError)

Error parsing a server response.

Validate(ValidateError)

Command inputs were not valid IMAP strings.

Append

Error appending an e-mail.

Unexpected(Response<'static>)

An unexpected response was received. This could be a response from a command, or an unsolicited response that could not be converted into a local type in UnsolicitedResponse.

MissingStatusResponse

In response to a STATUS command, the server sent OK without actually sending any STATUS responses first.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn StdError>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<Error> for Error

fn from(err: IoError) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: TlsError) -> Error

Converts to this type from the input type.

impl From<HandshakeError<TcpStream>> for Error

fn from(err: TlsHandshakeError<TcpStream>) -> Error

Converts to this type from the input type.

impl<T> From<IntoInnerError<T>> for Error

fn from(err: BufError<T>) -> Error

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(err: ParseError) -> Error

Converts to this type from the input type.

impl<'a> From<Response<'a>> for Error

fn from(err: Response<'a>) -> Error

Converts to this type from the input type.
