[][src]Enum sequoia_openpgp::KeyHandle

pub enum KeyHandle {

Identifies OpenPGP keys.

An KeyHandle is either a Fingerprint or a KeyID.



A Fingerprint.


A KeyID.


impl KeyHandle[src]

pub fn to_hex(&self) -> String[src]

Converts the key handle to a hexadecimal number.

pub fn as_slice(&self) -> &[u8][src]

Returns a reference to the raw identifier.

pub fn aliases<H>(&self, other: H) -> bool where
    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(&fpr2));
