Account index for SLIP-010 derivation

Implementations

impl TxInit

pub fn new(account_index: u32, num_rings: u8) -> Self

Create a new TxInit request

Trait Implementations

impl ApduStatic for TxInit

const CLA: u8 = 171u8

Class ID for APDU commands

const INS: u8 = 32u8

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 TxInit

fn clone(&self) -> TxInit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TxInit

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

Formats the value using the given formatter.

impl<'dec> Decode<'dec> for TxInit

type Output = TxInit

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 TxInit

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<TxInit> for TxInit

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