Variants

V(DkimVersion<'hdr>)

Required - Version

A(DkimAlgorithm<'hdr>)

Signature Algorithm - see s. 3.3 & IANA

B(&'hdr str)

Signature data in base64 (note about FWS in s. 3.5 b=)

Bh(&'hdr str)

Hash of canonicalized body part of the message as limited by the ‘l=’ Body length limit tag - base64. Note: Whitespaces / WHS are ignored

C(DkimCanonicalization<'hdr>)

Required - Message canonicalization informs the verifier of the type of canonicalization used to prepare the message for signing. See s.3.4

D(&'hdr str)

Required - The SDID claiming responsibility for an introduction of a message into the mail stream. The SDID MUST correspond to a valid DNS name under which the DKIM key ecord is published.

H(&'hdr str)

Required - Signed header fields separated by colon ‘:’ - see ‘h=’

I(&'hdr str)

Optional - The Agent or User Identifier (AUID) on behalf of which the SDID is taking responsibility.

L(&'hdr str)

Optional - Body length limit - see misuse on RFC 6376 s. 8.2.

Q(&'hdr str)

Optional - Query method - currently only Dns.

S(&'hdr str)

Required - The selector subdividing the namespace for the “d=” (domain) tag. Internationalized selector names MUST be encoded as A-labels, as described in Section 2.3 of RFC 5890.

T(DkimTimestamp<'hdr>)

Recommended - Signature Timestamp

X(DkimTimestamp<'hdr>)

Recommended - Signature Expiration

Z(&'hdr str)

Optional - Copied header fields

Atps(&'hdr str)

RFC 6541

Atpsh(&'hdr str)

RFC 6541

R(&'hdr str)

RFC 6651

Rfc5322From(&'hdr str)

RFC 5322

Unknown(&'hdr str, &'hdr str)

Unknown

Trait Implementations

impl<'hdr> Clone for DkimHeader<'hdr>

fn clone(&self) -> DkimHeader<'hdr>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'hdr> Debug for DkimHeader<'hdr>

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

Formats the value using the given formatter.

impl<'hdr> PartialEq for DkimHeader<'hdr>

fn eq(&self, other: &DkimHeader<'hdr>) -> 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.
