Struct yasna::models::TaggedDerValue

pub struct TaggedDerValue { /* fields omitted */ }

Container for a tag and arbitrary DER value.

When obtained by BERReader::read_tagged_der in DER mode, the reader verifies that the payload is actually valid DER. When constructed from bytes, the caller is responsible for providing valid DER.

Implementations

impl TaggedDerValue

pub fn from_octetstring(bytes: Vec<u8>) -> Self

Constructs a new TaggedDerValue as an octet string

pub fn from_tag_and_bytes(tag: Tag, bytes: Vec<u8>) -> Self

Constructs a new TaggedDerValue from its tag and content

pub fn from_tag_pc_and_bytes(tag: Tag, pcbit: PCBit, bytes: Vec<u8>) -> Self

Constructs a new TaggedDerValue from its tag, primitive/constructed bit, and content

pub fn tag(&self) -> Tag

Returns the tag

pub fn pcbit(&self) -> PCBit

Returns the primitive/constructed bit

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

Returns the value

pub fn as_bytes(&self) -> Option<&[u8]>

If the value is something that contains raw bytes, returns its content.

Examples

use yasna::models::TaggedDerValue;
let value = TaggedDerValue::from_octetstring(vec![1, 2, 3, 4, 5, 6]);
assert!(value.as_bytes() == Some(&[1, 2, 3, 4, 5, 6]));

pub fn as_str(&self) -> Option<&str>

If the value is something string-like, returns it as string.
