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

Methods

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.

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

Performs copy-assignment from source.

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 ==.

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

This method tests for !=.

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.

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

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

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

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

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

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

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

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

impl Ord for Tag

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

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

🔬 This is a nightly-only experimental API. (clamp)

Returns max if self is greater than max, and min if self is less than min. Otherwise this will return self. Panics if min > max.

impl Eq for Tag

impl Copy for Tag

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 Debug for Tag

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

Formats the value using the given formatter.
