Struct yasna::Tag

pub struct Tag {
    pub tag_class: TagClass,
    pub tag_number: u64,
}

An ASN.1 tag.

An ASN.1 tag is a pair of a tag class and a tag number.

• A tag class is one of:
  • UNIVERSAL
  • APPLICATION
  • context specific
  • PRIVATE
• A tag number is a nonnegative integer. In this library. Tag numbers are assumed to be in u64.

Fields

tag_class: TagClass

The tag class

tag_number: u64

The tag number

Implementations

impl Tag

pub fn application(tag_number: u64) -> Tag

Constructs an APPLICATION tag, namely [APPLICATION n].

pub fn context(tag_number: u64) -> Tag

Constructs a context specific tag, namely [n].

pub fn private(tag_number: u64) -> Tag

Constructs a PRIVATE tag, namely [PRIVATE n].

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl Hash for Tag

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,

Feeds a slice of this type into the given Hasher.

impl Ord for Tag

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

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 ==.

const 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<Tag> for Tag

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

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

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

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

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

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

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

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

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

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