Struct sequoia_openpgp::packet::signature::subpacket::NotationData

pub struct NotationData { /* private fields */ }

Payload of a Notation Data subpacket.

The Notation Data subpacket provides a mechanism for a message’s signer to insert nearly arbitrary data into the signature. Because notations can be marked as critical, it is possible to add security relevant notations, which the receiving OpenPGP implementation will respect (in the sense that an implementation will reject signatures that include unknown, critical notations), even if they don’t understand the notations themselves.

It is possible to control how Sequoia’s higher-level functionality handles unknown, critical notations using a Policy object. Depending on the degree of control required, it may be sufficient to customize a StandardPolicy object using, for instance, the StandardPolicy::good_critical_notations method.

Notation names are human-readable UTF-8 strings. There are two namespaces: The user namespace and the IETF namespace. Names in the user namespace have the form name@example.org and are managed by the owner of the domain. Names in the IETF namespace may not contain an @ and are managed by IANA. See Section 5.2.3.16 of RFC 4880 for details.

Implementations

impl NotationData

pub fn new<N, V, F>(name: N, value: V, flags: F) -> Selfwhere
    N: AsRef<str>,
    V: AsRef<[u8]>,
    F: Into<Option<NotationDataFlags>>,

Creates a new Notation Data subpacket payload.

pub fn flags(&self) -> &NotationDataFlags

Returns the flags.

pub fn name(&self) -> &str

Returns the name.

pub fn value(&self) -> &[u8]

Returns the value.

Trait Implementations

impl Clone for NotationData

fn clone(&self) -> NotationData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NotationData

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

Formats the value using the given formatter.

impl Display for NotationData

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

Formats the value using the given formatter.

impl Hash for NotationData

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NotationData

fn cmp(&self, other: &NotationData) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<NotationData> for NotationData

fn eq(&self, other: &NotationData) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<NotationData> for NotationData

fn partial_cmp(&self, other: &NotationData) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
