    pub data: Cow<'a, [u8]>,
}

ASN.1 BITSTRING type

Fields

unused_bits: u8

data: Cow<'a, [u8]>

Implementations

impl<'a> BitString<'a>

pub const fn new(unused_bits: u8, s: &'a [u8]) -> BitString<'a>

pub fn is_set(&self, bitnum: usize) -> bool

Test if bit bitnum is set

Trait Implementations

impl AsRef<[u8]> for BitString<'_>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl CheckDerConstraints for BitString<'_>

fn check_constraints(any: &Any<'_>) -> Result<(), Error>

impl<'a> Clone for BitString<'a>

fn clone(&self) -> BitString<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for BitString<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for BitString<'a>

fn eq(&self, other: &BitString<'a>) -> 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 BitString<'_>

const TAG: Tag = Tag::BitString

impl ToDer for BitString<'_>

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

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

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

Attempt to write the DER header to this writer.

fn write_der_content( &self, writer: &mut dyn Write, ) -> Result<usize, SerializeError>

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

fn to_der_vec(&self) -> Result<Vec<u8>, SerializeError>

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

fn to_der_vec_raw(&self) -> Result<Vec<u8>, SerializeError>

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) -> Result<usize, SerializeError>

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

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

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 BitString<'a>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(any: &'b Any<'a>) -> Result<BitString<'a>, Error>

Performs the conversion.

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

type Error = Error

The type returned in the event of a conversion error.

fn try_from(any: Any<'a>) -> Result<BitString<'a>, Error>

Performs the conversion.
