Available on crate feature ctap2 only.

Represents a connection to a single FIDO token over a Transport.

This is a low level interface to FIDO tokens, passing raw messages. crate::ctap2 provides a higher level abstraction.

Required Associated Types

type Id: Sized + Debug + Sync + Send

Required Methods

fn get_transport(&self) -> AuthenticatorTransport

Gets the transport layer used for communication with this token.

fn transmit_raw<'life0, 'life1, 'life2, 'async_trait, U>( &'life0 mut self, cbor: &'life1 [u8], ui: &'life2 U ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, WebauthnCError>> + Send + 'async_trait>>

where U: UiCallback + 'async_trait, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Transmits a command on the underlying transport.

cbor is a CBOR-encoded command.

Interfaces need to check for and return any transport-layer-specific error code WebauthnCError::Ctap, but don’t need to worry about deserialising CBOR.

fn cancel<'life0, 'async_trait>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = Result<(), WebauthnCError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Cancels a pending request.

fn init<'life0, 'async_trait>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = Result<(), WebauthnCError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Initializes the Token

fn close<'life0, 'async_trait>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = Result<(), WebauthnCError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Closes the Token

Provided Methods

fn has_button(&self) -> bool

fn transmit<'a, 'life0, 'life1, 'async_trait, C, R, U>( &'life0 mut self, cmd: C, ui: &'life1 U ) -> Pin<Box<dyn Future<Output = Result<R, WebauthnCError>> + Send + 'async_trait>>

where C: CBORCommand<Response = R> + 'async_trait, R: CBORResponse + 'async_trait, U: UiCallback + 'async_trait, Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Transmit a CBOR message to a token, and deserialises the response.
