Expand description

An error that occurred while parsing a directory object of some kind.

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.

Internal(Pos)

An internal error in the parser: these should never happen.

MissingKeyword(Pos)

An entry was found with no keyword.

TruncatedLine(Pos)

An entry was found with no newline at the end.

BadKeyword(Pos)

A bad string was found in the keyword position.

BadObjectBeginTag(Pos)

We found an ill-formed “BEGIN FOO” tag.

BadObjectEndTag(Pos)

We found an ill-formed “END FOO” tag.

BadObjectMismatchedTag(Pos)

We found a “BEGIN FOO” tag with an “END FOO” tag that didn’t match.

BadObjectBase64(Pos)

We found a base64 object with an invalid base64 encoding.

DuplicateToken(&'static str, Pos)

The document is not supposed to contain more than one of some kind of entry, but we found one anyway.

UnexpectedToken(&'static str, Pos)

The document is not supposed to contain any of some particular kind of entry, but we found one anyway.

MissingToken(&'static str)

The document is supposed to contain any of some particular kind of entry, but we didn’t find one one anyway.

MisplacedToken(&'static str, Pos)

The document was supposed to have one of these, but not where we found it.

TooManyArguments(&'static str, Pos)

We found more arguments on an entry than it is allowed to hav.e

TooFewArguments(&'static str, Pos)

We didn’t fine enough arguments for some entry.

UnexpectedObject(&'static str, Pos)

We found an object attached to an entry that isn’t supposed to have one.

MissingObject(&'static str, Pos)

An entry was supposed to have an object, but it didn’t.

WrongObject(Pos)

We found an object on an entry, but the type was wrong.

MissingArgument(Pos)

We tried to find an argument that we were sure would be there, but it wasn’t!

This error should never occur in correct code; it should be caught earlier by TooFewArguments.

BadArgument(Pos, String)

We found an argument that couldn’t be parsed.

BadObjectVal(Pos, String)

We found an object that couldn’t be parsed after it was decoded.

BadSignature(Pos)

There was some signature that we couldn’t validate.

BadTorVersion(Pos)

There was a tor version we couldn’t parse.

BadPolicy(Pos, PolicyError)

There was an ipv4 or ipv6 policy entry that we couldn’t parse.

Untimely(Pos, TimeValidityError)

An object was expired or not yet valid.

Undecodable(Pos, Error)

An underlying byte sequence couldn’t be decoded.

BadDocumentVersion(u32)

Versioned document with an unrecognized version.

BadDocumentType

Unexpected document type

WrongStartingToken(String, Pos)

Document or section started with wrong token

WrongEndingToken(String, Pos)

Document or section ended with wrong token

WrongSortOrder(Pos)

Items not sorted as expected

InvalidLifetime

A consensus lifetime was ill-formed.

CannotBuild(&'static str)

We’re unable to finish building an object, for some reason.
