pub struct BERReaderSeq<'a, 'b>where
    'a: 'b,
{ /* private fields */ }
Expand description

A reader object for a sequence of BER/DER-encoded ASN.1 data.

The main source of this object is the read_sequence method from BERReader.

Examples

use yasna;
let data = &[48, 6, 2, 1, 10, 1, 1, 255];
let asn = yasna::parse_der(data, |reader| {
    reader.read_sequence(|reader| {
        let i = try!(reader.next().read_i64());
        let b = try!(reader.next().read_bool());
        return Ok((i, b));
    })
}).unwrap();
assert_eq!(asn, (10, true));

Implementations

Tells which format we are parsing, BER or DER.

Generates a new BERReader.

Tries to read an ASN.1 value. If it fails at the first tag, it doesn’t consume buffer and returns None.

Used to parse OPTIONAL elements.

Examples
use yasna;
let data = &[48, 3, 1, 1, 255];
let asn = yasna::parse_der(data, |reader| {
    reader.read_sequence(|reader| {
        let i = try!(reader.read_optional(|reader| {
            reader.read_i64()
        }));
        let b = try!(reader.next().read_bool());
        return Ok((i, b));
    })
}).unwrap();
assert_eq!(asn, (None, true));

Similar to read_optional, but uses default if it fails.

T: Eq is required because it fails in DER mode if the read value is equal to default.

Used to parse DEFAULT elements.

Examples
use yasna;
let data = &[48, 3, 1, 1, 255];
let asn = yasna::parse_der(data, |reader| {
    reader.read_sequence(|reader| {
        let i = try!(reader.read_default(10, |reader| {
            reader.read_i64()
        }));
        let b = try!(reader.next().read_bool());
        return Ok((i, b));
    })
}).unwrap();
assert_eq!(asn, (10, true));
