Struct asn1_der::DerObject

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

An untyped DER object

Methods

impl<'a> DerObject<'a>

pub fn new<S: Sink + Into<&'a [u8]>>(
    tag: u8,
    value: &[u8],
    sink: S
) -> Result<Self, Asn1DerError>

Writes a new DER object with tag and value into sink and returns a view over it

pub fn new_from_source<A: Source, B: Sink + Into<&'a [u8]>>(
    tag: u8,
    len: usize,
    value: &mut A,
    sink: B
) -> Result<Self, Asn1DerError>

Writes a new DER object with tag, len and value into sink and returns a view over it

pub fn decode(raw: &'a [u8]) -> Result<Self, Asn1DerError>

Decodes an object from raw

pub fn decode_from_source<A: Source, B: Sink + Into<&'a [u8]>>(
    source: &mut A,
    sink: B
) -> Result<Self, Asn1DerError>

Reads a DER-TLV structure from source by parsing the length field and copying the necessary bytes into sink and returns a view over it

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

The underlying raw slice

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

The object header

pub fn tag(self) -> u8

The object tag

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

The object value

pub fn encode<U: Sink>(&self, sink: &mut U) -> Result<(), Asn1DerError>

Encodes self to sink
