Struct asn1_cereal::tag::Tag

pub struct Tag {
    pub class: Class,
    pub tagnum: TagNum,
    pub constructed: bool,
}

A struct containing the information from an ASN.1 tag, which represents an ASN.1 element.

Fields

class: Class

The class flag in the ASN.1 tag.

tagnum: TagNum

The tag number in the ASN.1 tag.

constructed: bool

The constructed flag in the ASN.1 tag, indicating whether this element contains another ASN.1 element.

Methods

impl Tag

fn is_structured(&self) -> bool

Returns true when this element is a SEQUENCE (OF), or SET (OF).

fn read_tag<I: Iterator<Item=Result<u8>>>(bytes: &mut I) -> Result<Self, DecodeError>

Given an iterator over a byte stream, read and return a Tag struct.

fn write_tag<W: Write>(self, writer: &mut W) -> Result<(), EncodeError>

Write this ASN.1 Tag struct to the given writer.
