Struct CommandApdu 

pub struct CommandApdu { /* private fields */ }

Owned encoded command; Debug is redacted and its buffer is wiped on drop.

Implementations

impl CommandApdu

pub fn encode( header: ApduHeader, data: &[u8], le: ExpectedLength, encoding: ApduEncoding, ) -> Result<Self, Error>

Encode one complete physical APDU, copying data into a protected buffer.

This does not split a logical command or check channel/device capabilities. Use crate::operation::conversation for chaining and continuation.

Errors

Returns ErrorKind::InvalidArgument when data or Le exceeds the encoding range, or when Exact(0) is supplied.

Examples

use canokey_protocol::{ApduEncoding, ApduHeader, CommandApdu, ExpectedLength};
let command = CommandApdu::encode(
    ApduHeader::new(0, 0xcb, 0x3f, 0xff),
    &[0x5c, 1, 0x7e], ExpectedLength::Exact(256), ApduEncoding::Short,
)?;
assert_eq!(command.as_bytes(), &[0, 0xcb, 0x3f, 0xff, 3, 0x5c, 1, 0x7e, 0]);

pub fn as_bytes(&self) -> &[u8]

Borrow the complete encoded APDU. The caller sends these bytes unchanged.
