Struct CcidHost 

pub struct CcidHost<'d, A: UsbHostAllocator<'d>> { /* private fields */ }

Host driver for one USB CCID interface.

Implementations

impl<'d, A: UsbHostAllocator<'d>> CcidHost<'d, A>

pub fn new( alloc: &A, config_desc: &[u8], enum_info: &EnumerationInfo, ) -> Result<Self, CcidError>

Discover the CCID interface and allocate its bulk pipes.

pub fn info(&self) -> &CcidInfo

Discovered interface and endpoint information.

pub async fn get_slot_status( &mut self, slot: u8, ) -> Result<SlotStatus, CcidError>

Query one reader slot without changing card power or protocol state.

pub async fn power_off(&mut self, slot: u8) -> Result<SlotStatus, CcidError>

Power off one ICC slot.

pub async fn power_on( &mut self, slot: u8, voltage: u8, atr: &mut [u8], ) -> Result<usize, CcidError>

Activate one ICC slot and return its Answer to Reset (ATR).

voltage is the CCID bPowerSelect value; zero lets the reader choose.

pub async fn transfer_block( &mut self, slot: u8, apdu: &[u8], response: &mut [u8], ) -> Result<usize, CcidError>

Exchange one ISO 7816 APDU using PC_to_RDR_XfrBlock.

Returns the APDU response length, including its trailing SW1/SW2 bytes.
