Enum SignatureType

#[non_exhaustive]
pub enum SignatureType {
    Binary,
    Text,
    Standalone,
    GenericCertification,
    PersonaCertification,
    CasualCertification,
    PositiveCertification,

    Timestamp,
    Confirmation,
    Unknown(u8),
}

Signature type as defined in Section 5.2.1 of RFC 9580.

Examples

Use SignatureType to create a timestamp signature:

use sequoia_openpgp as openpgp;
use std::time::SystemTime;
use openpgp::packet::signature::SignatureBuilder;
use openpgp::types::SignatureType;

let mut builder = SignatureBuilder::new(SignatureType::Timestamp)
    .set_signature_creation_time(SystemTime::now())?;

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Binary

Signature over a binary document.

Text

Signature over a canonical text document.

Standalone

Standalone signature.

GenericCertification

Generic certification of a User ID and Public-Key packet.

PersonaCertification

Persona certification of a User ID and Public-Key packet.

CasualCertification

Casual certification of a User ID and Public-Key packet.

PositiveCertification

Positive certification of a User ID and Public-Key packet.

CertificationApproval

Certification Approval Key Signature (experimental).

Allows the certificate owner to attest to third party certifications. See Certification Approval Key Signature for details.

SubkeyBinding

Subkey Binding Signature

PrimaryKeyBinding

Primary Key Binding Signature

DirectKey

Signature directly on a key

KeyRevocation

Key revocation signature

SubkeyRevocation

Subkey revocation signature

CertificationRevocation

Certification revocation signature

Timestamp

Timestamp signature.

Confirmation

Third-Party Confirmation signature.

Unknown(u8)

Catchall.

Implementations

impl SignatureType

pub fn variants() -> impl Iterator<Item = Self>

Returns an iterator over all valid variants.

Returns an iterator over all known variants. This does not include the SignatureType::Unknown variants.

Trait Implementations

impl Clone for SignatureType

fn clone(&self) -> SignatureType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureType

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

Formats the value using the given formatter.

impl Display for SignatureType

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

Formats the value using the given formatter.

impl From<SignatureType> for u8

fn from(t: SignatureType) -> Self

Converts to this type from the input type.

impl From<u8> for SignatureType

fn from(u: u8) -> Self

Converts to this type from the input type.

impl Hash for SignatureType

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 SignatureType

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SignatureType

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for SignatureType

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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