Enum tor_bytes::Error

#[non_exhaustive]
pub enum Error {
    Truncated,
    ExtraneousBytes,
    BadLengthValue,
    BadMessage(&'static str),
    InvalidMessage(Cow<'static, str>),
    Bug(Bug),
}

Error type for decoding Tor objects from bytes.

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.

Truncated

Tried to read something, but we didn’t find enough bytes.

This can mean that the object is truncated, or that we need to read more and try again, depending on the context in which it was received.

ExtraneousBytes

Called Reader::should_be_exhausted(), but found bytes anyway.

BadLengthValue

Invalid length value

BadMessage(&'static str)

👎Deprecated since 0.6.2: Use InvalidMessage instead.

An attempt to parse an object failed for some reason related to its contents.

InvalidMessage(Cow<'static, str>)

An attempt to parse an object failed for some reason related to its contents.

Bug(Bug)

A parsing error that should never happen.

We use this one in lieu of calling assert() and expect() and unwrap() from within parsing code.

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)>

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<Bug> for Error

fn from(source: Bug) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
