Struct ExplicitTag

pub struct ExplicitTag<T> { /* private fields */ }

Explicit tag is quite often use in microsoft specification

Implementations

impl<T> ExplicitTag<T>

pub fn new(tag: Tag, inner: T) -> Self

Create a new explicit tag

Example

extern crate yasna;
use rdp::nla::asn1::{ExplicitTag, Integer};
use yasna::Tag;
let s = ExplicitTag::new(Tag::context(0), 2 as Integer);

pub fn inner(self) -> T

return the inner object

Trait Implementations

impl<T: ASN1> ASN1 for ExplicitTag<T>

fn write_asn1(&self, writer: DERWriter<'_>) -> RdpResult<()>

Write an ASN1 Node with an explicit tag using a DERWriter

Example

    let s = ExplicitTag::new(Tag::context(0), vec![0, 1, 2, 3]);
    assert_eq!(to_der(&s), [160, 6, 4, 4, 0, 1, 2, 3]);

fn read_asn1(&mut self, reader: BERReader<'_, '_>) -> RdpResult<()>

Read an ASN1 Explicit tag using a BerReader

Example

    let mut s = ExplicitTag::new(Tag::context(0), OctetString::new());
    from_der(&mut s, &[160, 6, 4, 4, 0, 1, 2, 3]).unwrap();
    assert_eq!(s.inner().len(), 4);

fn visit(&self) -> ASN1Type<'_>

Allow to cast the ASN1 inner type

Example

    let mut s = ExplicitTag::new(Tag::context(0), OctetString::new());
    from_der(&mut s, &[160, 6, 4, 4, 0, 1, 2, 3]).unwrap();
    assert_eq!(cast!(ASN1Type::OctetString, s).unwrap(), &[0, 1, 2, 3]);
