Enum tor_cell::Error

#[non_exhaustive]
pub enum Error {
    BytesErr {
        err: Error,
        parsed: &'static str,
    },
    EncodeErr(EncodeError),
    Internal(Bug),
    ChanProto(String),
    CircProto(String),
    BadStreamAddress,
    CantEncode(&'static str),
}

An error type for the tor-cell crate.

This type should probably be split into several. There’s more than one kind of error that can occur while doing something with tor cells.

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.

BytesErr

An error that occurred in the tor_bytes crate while decoding an object.

Fields

err: Error

The error that occurred.

parsed: &'static str

The thing that was being parsed.

EncodeErr(EncodeError)

We encountered an error while encoding an outgoing message.

This is likely to be a bug in somebody’s code: either the code in this crate, or in the calling code that provided an unencodable message.

Internal(Bug)

There was a programming error somewhere in the code.

ChanProto(String)

Protocol violation at the channel level

CircProto(String)

Protocol violation at the circuit level

BadStreamAddress

Tried to make or use a stream to an invalid destination address.

CantEncode(&'static str)

Tried to construct a message that Tor can’t represent.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 From<EncodeError> for Error

fn from(source: EncodeError) -> Self

Converts to this type from the input type.

impl HasKind for Error

fn kind(&self) -> ErrorKind

Return the kind of this error.
