Struct Tag 

pub struct Tag { /* private fields */ }

Content of a tagged item, CBOR major type 6.

A tag pairs an unsigned integer, which carries the semantic meaning registered for it, with the single data item it applies to.

Example

use cbor_next::{DataItem, Tag};

let content = Tag::new(1, 1_363_896_240);
assert_eq!(content.number(), 1);
assert_eq!(content.content(), &DataItem::from(1_363_896_240));

Implementations

impl Tag

pub fn new(number: u64, content: impl Into<DataItem>) -> Self

Create a tag from its number and the item it applies to.

pub fn number(&self) -> u64

The number of the tag.

pub fn set_number(&mut self, number: u64)

Replace the number of the tag.

pub fn content(&self) -> &DataItem

The item the tag applies to.

pub fn content_mut(&mut self) -> &mut DataItem

The item the tag applies to, mutably.

pub fn into_content(self) -> DataItem

Take ownership of the item the tag applies to.
