Struct Tag

pub struct Tag(/* private fields */);

CBOR data item tag.

See IanaTag for currently known tag values which have been registered.

Implementations

impl Tag

impl Clone for Tag

fn clone(&self) -> Tag

Returns a copy 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<'b, C> Decode<'b, C> for Tag

fn decode(d: &mut Decoder<'b>, _: &mut C) -> Result<Self, Error>

Decode a value using the given Decoder.

fn nil() -> Option<Self>

If possible, return a nil value of Self.

impl Display for Tag

Formats the value using the given formatter.

impl<C> Encode<C> for Tag

fn encode<W: Write>( &self, e: &mut Encoder<W>, _: &mut C, ) -> Result<(), Error<W::Error>>

Encode a value of this type using the given Encoder.

fn is_nil(&self) -> bool

Is this value of Self a nil value?

impl From<&IanaTag> for Tag

fn from(t: &IanaTag) -> Tag

Converts to this type from the input type.

impl From<&Tag> for u64

fn from(t: &Tag) -> Self

Converts to this type from the input type.

impl From<IanaTag> for Tag

fn from(t: IanaTag) -> Tag

Converts to this type from the input type.

impl From<Tag> for u64

fn from(t: Tag) -> Self

Converts to this type from the input type.

impl Hash for Tag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Tag

fn cmp(&self, other: &Tag) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for Tag

fn partial_cmp(&self, other: &Tag) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<Tag> for IanaTag

type Error = UnknownTag

The type returned in the event of a conversion error.

fn try_from(t: Tag) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Tag

impl Eq for Tag

impl StructuralPartialEq for Tag

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
