A CBOR data item.

See RFC 7049 § 1.2: Data item.

Variants

Integer

Fields

value: u64

The value of this unsigned integer.

bitwidth: IntegerWidth

The bitwidth used for encoding this integer.

An unsigned integer.

See RFC 7049 § 2.1: Major type 0.

Negative

Fields

value: u64

The encoded value of this negative integer, the real value is -1 - value (requires use of i128 for full range support).

bitwidth: IntegerWidth

The bitwidth used for encoding this integer.

A negative integer.

See RFC 7049 § 2.1: Major type 0.

ByteString(ByteString)

A string of raw bytes with no direct attached meaning.

See the docs for ByteString for more details.

TextString(TextString)

A UTF-8 encoded text string.

See the docs for TextString for more details.

IndefiniteByteString(Vec<ByteString>)

A series of ByteString chunks encoded as an indefinite length byte string.

See RFC 7049 § 2.2.2.

IndefiniteTextString(Vec<TextString>)

A series of TextString chunks encoded as an indefinite length text string.

See RFC 7049 § 2.2.2.

Array

Fields

data: Vec<DataItem>

The data items in this array.

bitwidth: Option<IntegerWidth>

The bitwidth used for encoding the array length.

If has the value None then this array is encoded using the indefinite length form, see RFC 7049 § 2.2.1.

An array of data items.

See RFC 7049 § 2.1: Major type 4.

Map

Fields

data: Vec<(DataItem, DataItem)>

The pairs of data items in this map.

bitwidth: Option<IntegerWidth>

The bitwidth used for encoding the map length.

If has the value None then this map is encoded using the indefinite length form, see RFC 7049 § 2.2.1.

A map of pairs of data items.

See RFC 7049 § 2.1: Major type 5.

Tag

Fields

tag: Tag

The semantic tag to be applied to value.

bitwidth: IntegerWidth

The bitwidth used to encode the semantic tag.

value: Box<DataItem>

The data item which has the semantic tag applied to it.

Semantic tagging of another data item.

See the docs for Tag for more details.

Float

Fields

value: f64

The floating point value.

bitwidth: FloatWidth

The bitwidth used for encoding the value.

A floating point value.

See RFC 7049 § 2.3.

Simple(Simple)

A “simple value” data item.

See the docs for Simple for more details.

Implementations

impl DataItem

pub fn to_bytes(&self) -> Vec<u8>

impl DataItem

pub fn to_diag(&self) -> String

pub fn to_diag_pretty(&self) -> String

impl DataItem

pub fn to_hex(&self) -> String

Trait Implementations

impl Clone for DataItem

fn clone(&self) -> DataItem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataItem

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

Formats the value using the given formatter.

impl PartialEq<DataItem> for DataItem

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