[−][src]Enum sequoia_openpgp::KeyHandle
Identifies certificates and keys.
A KeyHandle
is either a Fingerprint
or a KeyID
.
Variants
Fingerprint(Fingerprint)
A Fingerprint.
KeyID(KeyID)
A KeyID.
Implementations
impl KeyHandle
[src]
pub fn as_bytes(&self) -> &[u8]
[src]
Returns a reference to the raw identifier.
pub fn aliases<H>(&self, other: H) -> bool where
H: Borrow<KeyHandle>,
[src]
H: Borrow<KeyHandle>,
Returns whether self
and other
could be aliases of each other.
KeyHandle
's PartialEq
implementation cannot assert that a
Fingerprint
and a KeyID
are equal, because distinct
fingerprints may have the same KeyID
, and PartialEq
must
be transitive, i.e.,
a == b and b == c implies a == c.
That is, if fpr1
and fpr2
are distinct fingerprints with the
same key ID then:
fpr1 == keyid and fpr2 == keyid, but fpr1 != fpr2.
In these cases (and only these cases) KeyHandle
's
PartialOrd
implementation returns None
to correctly
indicate that a comparison is not possible.
This definition of equality makes searching for a given
KeyHandle
using PartialEq
awkward. This function fills
that gap. It answers the question: given two KeyHandles
,
could they be aliases? That is, it implements the desired,
non-transitive equality relation:
// fpr1 and fpr2 are different fingerprints with the same KeyID. assert!(! fpr1.eq(&fpr2)); assert!(fpr1.aliases(&keyid)); assert!(fpr2.aliases(&keyid)); assert!(! fpr1.aliases(&fpr2));
