Struct SequenceIterator 

pub struct SequenceIterator<'a, T, F, E = Error>
where
    F: ASN1Parser,
{ /* private fields */ }

An Iterator over binary data, parsing elements of type T

This helps parsing SEQUENCE OF items of type T. The type of parser (BER/DER) is specified using the generic parameter F of this struct.

Note: the iterator must start on the sequence contents, not the sequence itself.

Examples

use asn1_rs::{DerParser, Integer, SequenceIterator};

let data = &[0x30, 0x6, 0x2, 0x1, 0x1, 0x2, 0x1, 0x2];
for (idx, item) in SequenceIterator::<Integer, DerParser>::new(&data[2..]).enumerate() {
    let item = item.unwrap(); // parsing could have failed
    let i = item.as_u32().unwrap(); // integer can be negative, or too large to fit into u32
    assert_eq!(i as usize, idx + 1);
}

Implementations

impl<'a, T, F, E> SequenceIterator<'a, T, F, E>

where F: ASN1Parser,

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

Trait Implementations

impl<'a, T: Debug, F, E: Debug> Debug for SequenceIterator<'a, T, F, E>

where F: ASN1Parser + Debug,

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
