Struct asn1_rs::Null

pub struct Null {}

ASN.1 NULL type

Implementations

impl Null

pub const fn new() -> Self

Trait Implementations

impl CheckDerConstraints for Null

fn check_constraints(_any: &Any<'_>) -> Result<()>

impl Debug for Null

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

Formats the value using the given formatter.

impl PartialEq for Null

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

const TAG: Tag = Tag::Null

impl ToDer for Null

fn to_der_len(&self) -> Result<usize>

Get the length of the object (including the header), when encoded

fn write_der_header(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER header to this writer.

fn write_der_content(&self, _writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER content (all except header) to this writer.

fn to_der_vec(&self) -> SerializeResult<Vec<u8>>

Write the DER encoded representation to a newly allocated Vec<u8>.

fn to_der_vec_raw(&self) -> SerializeResult<Vec<u8>>

Similar to using to_vec, but uses provided values without changes. This can generate an invalid encoding for a DER object.

fn write_der(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER encoded representation (header and content) into this writer.

fn write_der_raw(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Similar to using to_der, but uses provided values without changes. This can generate an invalid encoding for a DER object.

impl<'a, 'b> TryFrom<&'b Any<'a>> for Null

type Error = Error

The type returned in the event of a conversion error.

fn try_from(any: &'b Any<'a>) -> Result<Null>

Performs the conversion.

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

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.

impl DerAutoDerive for Null

impl Eq for Null

impl StructuralPartialEq for Null
