pub struct ComponentAmalgamationIter<'a, C> { /* private fields */ }
Expand description
An iterator over components.
Using the ComponentAmalgamationIter::with_policy
, it is
possible to change the iterator to only return
ComponentAmalgamation
s for valid components. In this case,
ComponentAmalgamationIter::with_policy
transforms the
ComponentAmalgamationIter
into a
ValidComponentAmalgamationIter
, which returns
ValidComponentAmalgamation
s. ValidComponentAmalgamation
offers additional filters.
ComponentAmalgamationIter
follows the builder pattern. There is
no need to explicitly finalize it: it already implements the
Iterator
trait.
A ComponentAmalgamationIter
is returned by Cert::userids
,
Cert::user_attributes
, and Cert::unknowns
.
(Cert::keys
returns a KeyAmalgamationIter
.)
Examples
Iterate over the User IDs in a certificate:
use openpgp::cert::prelude::*;
// Iterate over all User IDs.
for ua in cert.userids() {
// ua is a `ComponentAmalgamation`, specifically, a `UserIDAmalgamation`.
}
Only return valid User IDs.
use openpgp::cert::prelude::*;
use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();
// Iterate over all valid User IDs.
for ua in cert.userids().with_policy(p, None) {
// ua is a `ValidComponentAmalgamation`, specifically, a
// `ValidUserIDAmalgamation`.
}
Implementations§
source§impl<'a, C> ComponentAmalgamationIter<'a, C>
impl<'a, C> ComponentAmalgamationIter<'a, C>
sourcepub fn with_policy<T>(
self,
policy: &'a dyn Policy,
time: T
) -> ValidComponentAmalgamationIter<'a, C> ⓘwhere
T: Into<Option<SystemTime>>,
pub fn with_policy<T>(
self,
policy: &'a dyn Policy,
time: T
) -> ValidComponentAmalgamationIter<'a, C> ⓘwhere
T: Into<Option<SystemTime>>,
Changes the iterator to only return components that are valid according to the policy at the specified time.
If time
is None, then the current time is used.
Refer to the ValidateAmalgamation
trait for a definition
of a valid component.
Examples
use openpgp::cert::prelude::*;
use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();
// Iterate over all valid User Attributes.
for ua in cert.user_attributes().with_policy(p, None) {
// ua is a `ValidComponentAmalgamation`, specifically, a
// `ValidUserAttributeAmalgamation`.
