Struct iso7816_tlv::simple::Tlv

pub struct Tlv { /* fields omitted */ }

SIMPLE-TLV data object representation.

Each SIMPLE-TLV data object shall consist of two or three consecutive fields: a mandatory tag field, a mandatory length field and a conditional value field

Methods

impl Tlv

pub fn new(tag: Tag, value: Value) -> Result<Self, TlvError>

Create a SIMPLE-TLV data object from valid tag and value. A value has a maximum size of 65_535 bytes. Otherwise this fonction fails with TlvError::InvalidLength.

pub fn to_vec(&self) -> Vec<u8>

serializes self into a byte vector.

pub fn parse(input: &[u8]) -> (Result<Self, TlvError>, &[u8])

Parses a byte array into a SIMPLE-TLV structure. This also returns the unprocessed data.

pub fn from_bytes(input: &[u8]) -> Result<Self, TlvError>

Parses a byte array into a SIMPLE-TLV structure. Input must exactly match a SIMPLE-TLV object.

Trait Implementations

impl Clone for Tlv

fn clone(&self) -> Tlv

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Tlv> for Tlv

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

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

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

impl Debug for Tlv

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

Formats the value using the given formatter.
