Struct basn1::der::reader::Reader

pub struct Reader<'a> { /* fields omitted */ }

ASN.1 DER Reader on slice

Implementations

impl<'a> Reader<'a>

pub fn new(slice: &'a [u8]) -> Self

Create a new DER Reader where the read buffer is given by the user

pub fn anything(&mut self) -> Result<(Identifier, Length, &'a [u8]), Error>

Get the next Tag / Length / Value triple, whichever it is

pub fn bool(&mut self) -> Result<bool, Error>

Get the next boolean from the stream

pub fn integer(&mut self) -> Result<&'a Integer, Error>

Get the next integer from the stream

pub fn enumerated(&mut self) -> Result<&'a Enumerated, Error>

Get the next enumerated from the stream

pub fn bitstring(&mut self) -> Result<&'a BitString, Error>

Get the next bitstring from the stream

pub fn octetstring(&mut self) -> Result<&'a [u8], Error>

Get the next octetstring from the stream

pub fn utf8_string(&mut self) -> Result<&'a str, Error>

Get the next utf8 string from the stream

pub fn null(&mut self) -> Result<(), Error>

Get the next null from the stream

pub fn oid(&mut self) -> Result<&'a OID, Error>

Get the next OID from the stream

pub fn sequence(&mut self) -> Result<Reader<'a>, Error>

Get the next sequence from the stream as a Reader

pub fn set<A, F>(&mut self, f: F) -> Result<Set<'a, F>, Error> where
    F: Fn(Reader<'a>) -> Result<A, Error>, 

Get the next set from the stream as a Set iterator

pub fn done(&self) -> Result<(), Error>

Check is the stream is done

If the reader is not finished, then the Error::ReaderNotTerminated is returned

pub fn current_position(&self) -> usize

Get the position of the reader in the slice

pub fn remaining(&self) -> &'a [u8]

Get the remaining buffer as a slice

Trait Implementations

impl<'a> Clone for Reader<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.
