Expand description

Device provides a high-level interface exchanging APDU objects with implementers of Exchange

Required Methods§

Source

fn request<'a, 'b, 'life0, 'async_trait, RESP>( &'life0 mut self, request: impl 'async_trait + ApduReq<'a> + Send, buff: &'b mut [u8], timeout: Duration, ) -> Pin<Box<dyn Future<Output = Result<RESP, Error>> + Send + 'async_trait>>
where RESP: 'async_trait + EncDec<'b, ApduError>, Self: 'async_trait, 'a: 'async_trait, 'b: 'async_trait, 'life0: 'async_trait,

Issue a request APDU, returning a reponse APDU

Provided Methods§

Source

fn app_info<'life0, 'async_trait>( &'life0 mut self, timeout: Duration, ) -> Pin<Box<dyn Future<Output = Result<AppInfo, Error>> + Send + 'async_trait>>
where Self: Send + 'async_trait, 'life0: 'async_trait,

Fetch application information

Source

fn device_info<'life0, 'async_trait>( &'life0 mut self, timeout: Duration, ) -> Pin<Box<dyn Future<Output = Result<DeviceInfo, Error>> + Send + 'async_trait>>
where Self: Send + 'async_trait, 'life0: 'async_trait,

Fetch device information

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
