Struct coins_ledger::common::APDUAnswer

pub struct APDUAnswer { /* fields omitted */ }

An APDU response is a wrapper around some response bytes. To avoid unnecessary clones, it exposes the retcode and response data as getters.

Implementations

impl APDUAnswer

pub fn from_answer(response: Vec<u8>) -> Result<APDUAnswer, LedgerError>

instantiate a

pub fn len(&self) -> usize

Return the response length in bytes

pub fn is_empty(&self) -> bool

True if the underlying slice is empty, else false.

pub fn is_success(&self) -> bool

Return false if the response status is an error.

pub fn retcode(&self) -> u16

Get the integer response code from the response packet.

Panics if the buffer is too short (some device error).

pub fn response_status(&self) -> APDUResponseCodes

Return the Response code

Panics on unknown retcode.

pub fn data(&self) -> Option<&[u8]>

Return a reference to the response data, or None if the response errored
