Struct yasna::models::TaggedDerValue

pub struct TaggedDerValue { /* private fields */ }

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.

Trait Implementations

impl BERDecodable for TaggedDerValue

fn decode_ber(reader: BERReader<'_, '_>) -> ASN1Result<Self>

Reads an ASN.1 value from BERReader and converts it to Self.

impl Clone for TaggedDerValue

fn clone(&self) -> TaggedDerValue

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TaggedDerValue

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

Formats the value using the given formatter.

impl Hash for TaggedDerValue

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TaggedDerValue

fn cmp(&self, other: &TaggedDerValue) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for TaggedDerValue

fn eq(&self, other: &TaggedDerValue) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TaggedDerValue

fn partial_cmp(&self, other: &TaggedDerValue) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
