Struct asn1_rs::SequenceOf

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

The SEQUENCE OF object is an ordered list of homogeneous types.

Examples

use asn1_rs::SequenceOf;
use std::iter::FromIterator;

// build set
let it = [2, 3, 4].iter();
let seq = SequenceOf::from_iter(it);

// `seq` now contains the serialized DER representation of the array

// iterate objects
let mut sum = 0;
for item in seq.iter() {
    // item has type `Result<u32>`, since parsing the serialized bytes could fail
    sum += *item;
}
assert_eq!(sum, 9);

Implementations

impl<T> SequenceOf<T>

pub const fn new(items: Vec<T>) -> Self

Builds a SEQUENCE OF from the provided content

pub fn len(&self) -> usize

Returns the length of this SEQUENCE (the number of items).

pub fn is_empty(&self) -> bool

Returns true if this SEQUENCE is empty.

pub fn iter(&self) -> impl Iterator<Item = &T>

Returns an iterator over the items of the SEQUENCE.

Trait Implementations

impl<'a, T> AsRef<[T]> for SequenceOf<T>

fn as_ref(&self) -> &[T]

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> CheckDerConstraints for SequenceOf<T> where
    T: CheckDerConstraints, 

fn check_constraints(any: &Any<'_>) -> Result<()>

impl<T: Debug> Debug for SequenceOf<T>

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

Formats the value using the given formatter.

impl<T> From<SequenceOf<T>> for Vec<T>

fn from(set: SequenceOf<T>) -> Self

Converts to this type from the input type.

impl<T> FromIterator<T> for SequenceOf<T>

fn from_iter<IT: IntoIterator<Item = T>>(iter: IT) -> Self

Creates a value from an iterator.

impl<'a, T> IntoIterator for &'a SequenceOf<T>

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = Iter<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Iter<'a, T>

Creates an iterator from a value.

impl<'a, T> IntoIterator for &'a mut SequenceOf<T>

type Item = &'a mut T

The type of the elements being iterated over.

type IntoIter = IterMut<'a, T>

Which kind of iterator are we turning this into?

impl<T> Tagged for SequenceOf<T>

const TAG: Tag = Tag::Sequence

impl<T> ToDer for SequenceOf<T> where
    T: ToDer, 

fn to_der_len(&self) -> Result<usize>

Get the length of the object, when encoded

fn write_der_header(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER header to this writer.

fn write_der_content(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER content (all except header) to this writer.

fn to_der_vec(&self) -> SerializeResult<Vec<u8>>

Write the DER encoded representation to a newly allocated Vec<u8>.

fn to_der_vec_raw(&self) -> SerializeResult<Vec<u8>>

Similar to using to_vec, but uses provided values without changes. This can generate an invalid encoding for a DER object.

fn write_der(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER encoded representation (header and content) into this writer.

fn write_der_raw(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Similar to using to_der, but uses provided values without changes. This can generate an invalid encoding for a DER object.

    T: FromBer<'a>, 

type Error = Error

fn try_from(any: Any<'a>) -> Result<Self>

Performs the conversion.
