Represents a component under a given policy.

Required methods

`fn cert(&self) -> &'a Cert`

Returns the certificate that the component came from.

`fn time(&self) -> SystemTime`

Returns the amalgamation's reference time.

For queries that are with respect to a point in time, this determines that point in time. For instance, if a component is created at t_c and expires at t_e, then ValidComponentAmalgamation::alive will return true if the reference time is greater than or equal to t_c and less than t_e.

`fn policy(&self) -> &'a dyn Policy`

Returns the amalgamation's policy.

`fn with_policy<T>(self, policy: &'a dyn Policy, time: T) -> Result<Self> where Self: Sized, T: Into<Option<SystemTime>>,`

Changes the amalgamation's policy.

If time is None, the current time is used.

`fn binding_signature(&self) -> &'a Signature`

Returns the component's binding signature as of the reference time.

`fn direct_key_signature(&self) -> Option<&'a Signature>`

Returns the Certificate's direct key signature as of the reference time, if any.

Subpackets on direct key signatures apply to all components of the certificate.

`fn revoked(&self) -> RevocationStatus<'a>`

Returns the component's revocation status as of the amalgamation's reference time.

Note: this does not return whether the certificate is valid.

Provided methods

`fn cert_revoked(&self) -> RevocationStatus<'a>`

Returns the certificate's revocation status as of the amalgamtion's reference time.

`fn cert_alive(&self) -> Result<()>`

Returns whether the certificateis alive as of the amalgamtion's reference time.

`fn map<F: Fn(&'a Signature) -> Option<T>, T>(&self, f: F) -> Option<T>`

Maps the given function over binding and direct key signature.

Makes f consider both the binding signature and the direct key signature. Information in the binding signature takes precedence over the direct key signature. See also Section 5.2.3.3 of RFC 4880.

`fn key_flags(&self) -> Option<KeyFlags>`

Returns the key's key flags as of the amalgamtion's reference time.

Considers both the binding signature and the direct key signature. Information in the binding signature takes precedence over the direct key signature. See also Section 5.2.3.3 of RFC 4880.

`fn has_any_key_flag<F>(&self, flags: F) -> bool where F: Borrow<KeyFlags>,`

Returns whether the key has at least one of the specified key flags as of the amalgamtion's reference time.
