Struct red_asn1::Tag

pub struct Tag {
    pub number: u8,
    pub type: TagType,
    pub class: TagClass,
}

Class to represent DER-ASN1 tags of the different types.

Each tag is divided into 3 parts:

• Class: If tag is of an Primitive or Constructed object
• Type: The scope of the object
• Number: A distinguished number between objects of the same type and class

Fields

number: u8

type: TagType

class: TagClass

Implementations

impl Tag

pub fn new(number: u8, r#type: TagType, class: TagClass) -> Tag

Creates a new tag from a given number, type and class

pub fn new_primitive_universal(number: u8) -> Tag

Shorcut of: Tag::new(tag_number, TagType::Primitive, TagClass::Universal)

pub fn new_constructed_universal(number: u8) -> Tag

Shorcut of: Tag::new(tag_number, TagType::Constructed, TagClass::Universal)

pub fn build(&self) -> Vec<u8>

Produces an DER version of the tag in bytes

pub fn parse(raw: &[u8]) -> Result<(&[u8], Self)>

Set the Tag values from a array of bytes

Trait Implementations

impl Clone for Tag

pub fn clone(&self) -> Tag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Tag

impl Debug for Tag

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

Formats the value using the given formatter.

impl Default for Tag

pub fn default() -> Tag

Returns the "default value" for a type.

impl PartialEq<Tag> for Tag

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

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

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

This method tests for !=.
