Struct der::asn1::Null

pub struct Null;

ASN.1 NULL type.

Trait Implementations

impl Clone for Null

fn clone(&self) -> Null

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Null

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

Formats the value using the given formatter.

impl<'a> DecodeValue<'a> for Null

fn decode_value<R: Reader<'a>>(reader: &mut R, header: Header) -> Result<Self>

Attempt to decode this message using the provided Reader.

impl EncodeValue for Null

fn value_len(&self) -> Result<Length>

Compute the length of this value (sans Tag+Length header) when encoded as ASN.1 DER.

fn encode_value(&self, _writer: &mut dyn Writer) -> Result<()>

Encode value (sans Tag+Length header) as ASN.1 DER using the provided Writer.

fn header(&self) -> Result<Header>

where Self: Tagged,

Get the Header used to encode this value.

impl FixedTag for Null

const TAG: Tag = Tag::Null

ASN.1 tag

impl<'a> From<Null> for AnyRef<'a>

fn from(_: Null) -> AnyRef<'a>

Converts to this type from the input type.

impl Ord for Null

fn cmp(&self, other: &Null) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Null

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

impl PartialOrd for Null

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<AnyRef<'_>> for Null

type Error = Error

The type returned in the event of a conversion error.

fn try_from(any: AnyRef<'_>) -> Result<Null>

Performs the conversion.

impl Copy for Null

impl Eq for Null

impl StructuralPartialEq for Null
