Struct BitString 

pub struct BitString<'a> {
    pub unused_bits: u8,
    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]) -> Self

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<()>

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

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>

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 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>>

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>>

Performs the conversion.

impl DerAutoDerive for BitString<'_>

impl<'a> Eq for BitString<'a>

impl<'a> StructuralPartialEq for BitString<'a>

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.
