Struct asn1_der::DerObject

pub struct DerObject {
    pub tag: DerTag,
    pub value: DerValue,
}

A generic DER object

Fields

tag: DerTag

A DER tag that represents this object's type

value: DerValue

The DER object's payload

Methods

impl DerObject

pub fn new(tag: DerTag, value: DerValue) -> Self

Creates a new DER object from tag and value (the length is computed from value)

pub fn from_raw(tag: u8, bytes: impl Into<Vec<u8>>) -> Self

Creates a new DER object from tag and value (the length is computed from value)

Parameters:

• tag: The DER tag value that represents the object's type
• value: The DER payload bytes that this object should carry

pub fn deserialize<'a>(
    source: impl Iterator<Item = &'a u8>
) -> Result<Self, Asn1DerError>

DER-deserializes the data from source

pub fn serialized_len(&self) -> usize

The length of the DER-serialized representation of self

pub fn serialize<'a>(
    &self,
    buf: impl Iterator<Item = &'a mut u8>
) -> Result<usize, Asn1DerError>

DER-serializes self into buf and returns the amount of bytes written

pub fn compute_serialized_len(payload_len: usize) -> usize

Efficiently computes the length of the DER-serialized representation of an object with payload_len payload bytes
