Implementations

impl<'a> Command<'a>

pub fn new(cla: u8, ins: u8, p1: u8, p2: u8) -> Self

Constructs an command with CLA, INS, P1, and P2. No payloads will be transmitted or received.

pub fn new_with_le(cla: u8, ins: u8, p1: u8, p2: u8, le: u16) -> Self

Constructs an command with CLA, INS, P1, P2, and Le. A payload will be received.

pub fn new_with_payload( cla: u8, ins: u8, p1: u8, p2: u8, payload: &'a [u8], ) -> Self

Constructs an command with CLA, INS, P1, P2, and a payload. No payload will be received.

pub fn new_with_payload_le( cla: u8, ins: u8, p1: u8, p2: u8, le: u16, payload: &'a [u8], ) -> Self

Constructs an command with CLA, INS, P1, P2, Le, and a payload. A payload will be received.

pub fn write(&self, buf: &mut [u8])

Writes a serialised byte stream onto the mutable buffer.

pub fn len(&self) -> usize

Calculates the length of entire the command.
