Struct Tag 

pub struct Tag {
    pub class: TagClass,
    pub tag_type: TagType,
    pub number: u32,
}

A BER tag identifier.

Fields

class: TagClass

The tag class

tag_type: TagType

Whether this is a constructed type

number: u32

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl PartialEq for Tag

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