Struct TagNumber 

pub struct TagNumber(pub u32);

ASN.1 tag numbers (i.e. lower 5 bits of a Tag).

From X.690 Section 8.1.2.2:

bits 5 to 1 shall encode the number of the tag as a binary integer with bit 5 as the most significant bit.

This library supports tag numbers ranging from zero to 30 (inclusive) for universal tags and arbitrary 32-bit tag numbers for application, private and context-specific tags.

Section 8.1.2.4 describes how to support multi-byte tag numbers, which are encoded by using a leading tag number of 31 (0b11111).

Implementations

impl TagNumber

pub const fn new(value: u32) -> Self

👎Deprecated since 0.8.0:

use TagNumber(value) directly as inner field is now pub

Create a new tag number.

pub fn application(self, constructed: bool) -> Tag

Create an APPLICATION tag with this tag number.

pub fn context_specific(self, constructed: bool) -> Tag

Create a CONTEXT-SPECIFIC tag with this tag number.

pub fn private(self, constructed: bool) -> Tag

Create a PRIVATE tag with this tag number.

pub fn value(self) -> u32

Get the inner value.

Trait Implementations

impl Clone for TagNumber

fn clone(&self) -> TagNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TagNumber

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

Formats the value using the given formatter.

impl Display for TagNumber

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

Formats the value using the given formatter.

impl From<TagNumber> for u32

fn from(number: TagNumber) -> u32

Converts to this type from the input type.

impl From<u32> for TagNumber

fn from(value: u32) -> TagNumber

Converts to this type from the input type.

impl Hash for TagNumber

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 TagNumber

fn cmp(&self, other: &TagNumber) -> 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 TagNumber

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

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

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 TagNumber

fn partial_cmp(&self, other: &TagNumber) -> 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.
