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 Encodable for Null

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

Compute the length of this value in bytes when encoded as ASN.1 DER.

fn encode(&self, encoder: &mut Encoder<'_>) -> Result<()>

Encode this value as ASN.1 DER using the provided Encoder.

fn encode_to_slice<'a>(&self, buf: &'a mut [u8]) -> Result<&'a [u8]>

Encode this value to the provided byte slice, returning a sub-slice containing the encoded message.

fn encode_to_vec(&self, buf: &mut Vec<u8>) -> Result<Length>

This is supported on crate feature alloc only.

Encode this message as ASN.1 DER, appending it to the provided byte vector.

fn to_vec(&self) -> Result<Vec<u8>>

This is supported on crate feature alloc only.

Serialize this message as a byte vector.

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

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

Performs the conversion.

impl Ord for Null

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<Null> for Null

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

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

#[must_use]

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

This method tests for !=.

impl PartialOrd<Null> for Null

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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<Any<'_>> for Null

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.
