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

tag_number: u64

Methods

impl Tag

fn application(tag_number: u64) -> Tag

Constructs an APPLICATION tag, namely [APPLICATION n].

fn context(tag_number: u64) -> Tag

Constructs a context specific tag, namely [n].

fn private(tag_number: u64) -> Tag

Constructs a PRIVATE tag, namely [PRIVATE n].
