[−][src]Struct pcsc::ReaderState

#[repr(C)]pub struct ReaderState { /* fields omitted */ }

A structure for tracking the current state of card readers and cards.

This structure wraps SCARD_READERSTATE (pcsclite, MSDN).

Methods

impl ReaderState[src]

pub fn new<T: Into<CString>>(name: T, current_state: State) -> ReaderState[src]

Create a ReaderState for a card reader with a given presumed state.

pub fn name(&self) -> &CStr[src]

The name of the card reader.

pub fn atr(&self) -> &[u8][src]

The ATR (Answer To Reset) of the card inserted to the reader.

pub fn event_state(&self) -> State[src]

The last reported state.

pub fn event_count(&self) -> u32[src]

The card event count.

The count is incremented for each card insertion or removal in the reader. This can be used to detect a card removal/insertion between two calls to Context::get_status_change().

pub fn sync_current_state(&mut self)[src]

Sync the currently-known state to the last reported state.
