Methods

impl Tag

pub fn valid_start_of_message(&self) -> bool

Returns whether the Tag can be at the start of a valid message.

Certs can start with PublicKey, TSKs with a SecretKey.

Messages start with a OnePassSig, Signature (old style non-one pass signatures), PKESK, SKESK, CompressedData, or Literal.

Signatures can standalone either as a detached signature, a third-party certification, or a revocation certificate.

Trait Implementations

impl From<u8> for Tag

fn from(u: u8) -> Self

Performs the conversion.

impl From<Tag> for u8

fn from(t: Tag) -> u8

impl<'_> From<&'_ Tag> for u8

fn from(t: &Tag) -> u8

Performs the conversion.

impl Eq for Tag

impl PartialOrd<Tag> for Tag

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

impl Copy for Tag

impl PartialEq<Tag> for Tag

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

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

#[must_use]

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

This method tests for !=.

impl Clone for Tag

fn clone(&self) -> Tag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for Tag

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.
