Struct Der 

pub struct Der<'a> { /* private fields */ }

Sequential reader over concatenated DER elements.

Implementations

impl<'a> Der<'a>

pub fn new(data: &'a [u8]) -> Der<'a>

pub fn is_empty(&self) -> bool

pub fn peek_tag(&self) -> Option<u8>

pub fn read(&mut self) -> DerResult<Tlv<'a>>

pub fn expect(&mut self, tag: u8) -> DerResult<Tlv<'a>>

Reads an element and checks its tag.

pub fn optional(&mut self, tag: u8) -> DerResult<Option<Tlv<'a>>>

Reads the element only if the next tag matches.

pub fn sequence(&mut self) -> DerResult<Der<'a>>

pub fn oid(&mut self) -> DerResult<String>

pub fn uint(&mut self) -> DerResult<&'a [u8]>

INTEGER as unsigned big-endian bytes (leading zero stripped); rejects negatives.

pub fn small_uint(&mut self) -> DerResult<u64>

pub fn octet_string(&mut self) -> DerResult<&'a [u8]>

pub fn bit_string(&mut self) -> DerResult<&'a [u8]>

BIT STRING contents; requires zero unused bits.

Trait Implementations

impl<'a> Clone for Der<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Der<'a>

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

Formats the value using the given formatter.
