Errors returned by ARC parsers and the chain verifier.

Variants

MissingTag(String)

Header value missing a required tag.

InvalidTag(String)

Tag value malformed.

InvalidCv(String)

cv= value not one of none / pass / fail.

InvalidInstance(u32)

i= instance value out of range (must be 1-50 per RFC 8617 §4.2.1).

UnsupportedAlgorithm(String)

a= algorithm not supported.

NonContiguousChain

Sets in a chain are not contiguous from i=1.

Fields

missing: u32

First missing instance.

ChainTooLong(usize)

Chain has more than 50 sets (RFC 8617 §4.2.1 limit).

IncompleteSet

One of AAR / AMS / AS is missing for an instance number that appeared on another header.

Fields

instance: u32

Instance whose triplet is incomplete.

missing: &'static str

Which header type is missing ("aar" / "ams" / "seal").

Dns(String)

DNS lookup for the public key TXT record failed.

InvalidPublicKey(String)

Public-key TXT record present but unparseable.

SignatureMismatch

Cryptographic verification of an AMS or AS failed.

Fields

header: &'static str

Which header type’s signature failed.

instance: u32

Instance number whose signature failed.

BodyHashMismatch

AMS body hash (bh=) did not match the recomputed hash of the canonicalized body.

InvalidBase64(String)

A base64 tag (b= / bh=) failed to decode.

MalformedMessage

The raw message has no detectable end-of-headers terminator (no CRLF CRLF, no LF LF).

Trait Implementations

impl Clone for ArcError

fn clone(&self) -> ArcError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArcError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ArcError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ArcError

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 PartialEq for ArcError

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

Tests for self and other values to be equal, and is used by ==.

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

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