Enum DkimError 

pub enum DkimError {
    MissingHeader,
    MissingTag(String),
    InvalidTag(String),
    InvalidBase64(String),
    DnsTempError(String),
    DnsPermError(String),
    InvalidKey(String),
    UnsupportedAlgorithm(String),
    UnsupportedCanon(String),
    BodyHashMismatch,

}

Internal error category from the parser + verifier.

Variants

MissingHeader

DKIM-Signature header missing or malformed.

MissingTag(String)

Required tag (v, a, b, bh, d, h, s) missing.

InvalidTag(String)

Tag value couldn’t be parsed.

InvalidBase64(String)

Base64 decode failed for b= or bh=.

DnsTempError(String)

DNS lookup for selector failed.

DnsPermError(String)

DNS returned NXDOMAIN or unparseable TXT for selector.

InvalidKey(String)

Public key TXT record malformed.

UnsupportedAlgorithm(String)

Unsupported algorithm (we support rsa-sha256 in 1.0).

UnsupportedCanon(String)

Unsupported canonicalization combination.

BodyHashMismatch

Body hash (bh=) mismatch — body was modified in transit.

SignatureMismatch

Header signature failed RSA verify — body unchanged but headers / signature don’t match.

Expired

Signature expired (x= tag past).

Implementations

impl DkimError

pub fn to_result(&self) -> DkimResult

Map an error to the public DkimResult.

Trait Implementations

impl Clone for DkimError

fn clone(&self) -> DkimError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DkimError

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

Formats the value using the given formatter.

impl Display for DkimError

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

Formats the value using the given formatter.

impl Error for DkimError

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 DkimError

fn eq(&self, other: &DkimError) -> 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.
