Struct cbor_data::TaggedItem

pub struct TaggedItem<'a> { /* private fields */ }

Representation of a possibly tagged CBOR data item

You can obtain this representation using Cbor::tagged_item.

It holds an iterable representation of the tags, a decoded ItemKind and a reference to the underlying bytes for the whole item. Since all these are shallow references to existing data, this structure itself is Copy.

Implementations

impl<'a> TaggedItem<'a>

pub fn new(cbor: &'a Cbor) -> Self

pub fn decode(self) -> CborValue<'a>

Interpret the CBOR item at a higher level

While kind gives you precise information on how the item is encoded, this method interprets the tag-based encoding according to the standard, adding for example big integers, decimals, and floats, or turning base64-encoded text strings into binary strings.

pub fn tags(&self) -> Tags<'a>

An iterator over the tags of this item

pub fn kind(&self) -> ItemKind<'a>

A decoded form of the low-level representation of the CBOR item

pub fn cbor(&self) -> &'a Cbor

A reference to the underlying bytes from which this structure has been lifted

Trait Implementations

impl<'a> Clone for TaggedItem<'a>

fn clone(&self) -> TaggedItem<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TaggedItem<'a>

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

Formats the value using the given formatter.

impl<'a> Display for TaggedItem<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for TaggedItem<'a>

fn eq(&self, other: &TaggedItem<'a>) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
