Fields

ring_size: u8

Size of ring to be signed

real_index: u8

Index of real tx_in in ring

flags: TxRingInitFlags

Flags for ring init message

subaddress_index: u64

Subaddress of real tx_in, used for onetime_private_key recovery

value: u64

Ring value

token_id: u64

Ring token_id

onetime_private_key: TxOnetimeKey

One-time private key for pre-signed inputs etc. Zero if HAS_ONETIME_PRIVATE_KEY is not set

Implementations

impl TxRingInit

pub fn new( ring_size: u8, real_index: u8, subaddress_index: u64, value: u64, token_id: u64, onetime_private_key: Option<TxOnetimeKey> ) -> Self

Create a new ring initialisation request

pub fn hash(&self) -> [u8; 32]

Compute hash from TxRingInit object

Trait Implementations

impl ApduStatic for TxRingInit

const CLA: u8 = 171u8

Class ID for APDU commands

const INS: u8 = 64u8

Instruction ID for APDU commands

fn p1(&self) -> u8

Fetch P1 value (defaults to 0 if not extended)

fn p2(&self) -> u8

Fetch P2 value (defaults to 0 if not extended)

impl Clone for TxRingInit

fn clone(&self) -> TxRingInit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TxRingInit

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

Formats the value using the given formatter.

impl<'dec> Decode<'dec> for TxRingInit

type Output = TxRingInit

Output type (allows attaching lifetime bounds where required)

type Error = ApduError

Error type returned on parse error

fn decode(buff: &'dec [u8]) -> Result<(Self::Output, usize), Self::Error>

Decode consumes a slice and returns an object and decoded length.

impl Encode for TxRingInit

type Error = ApduError

Error type returned on parse error

fn encode_len(&self) -> Result<usize, Self::Error>

Calculate expected encoded length for an object

fn encode(&self, buff: &mut [u8]) -> Result<usize, Self::Error>

Encode method writes object data to the provided writer

impl PartialEq<TxRingInit> for TxRingInit

fn eq(&self, other: &TxRingInit) -> 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.
