}
Expand description
Error type for decoding Tor objects from bytes.
Variants (Non-exhaustive)§
This enum is marked as 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.
