Struct TpmResponder 

pub struct TpmResponder { /* private fields */ }

The responder end of a TpmTransport, for serving TPM commands.

Where a TpmDevice sends commands and receives responses, a TpmResponder receives commands and sends responses. Both ends share the same transport and frame codec; only the direction of use differs, which makes this crate usable for the TPM side of an exchange, such as an emulator.

Command decoding and response marshaling are left to the caller (for example via tpm2_protocol), keeping this type focused on transport and framing.

Implementations

impl TpmResponder

pub fn new(transport: Box<dyn TpmTransport>) -> Self

Creates a TpmResponder serving over the given transport.

pub fn recv_command(&mut self) -> Result<&[u8], TpmDeviceError>

Receives the next command frame, returning its raw bytes.

Errors

Returns UnexpectedEof when the peer disconnects, or other TpmDeviceError variants when the transport fails.

pub fn send_response(&mut self, frame: &[u8]) -> Result<(), TpmDeviceError>

Sends a marshaled response frame.

Errors

Returns a TpmDeviceError when the transport fails to send the frame.

pub fn serve<H>(&mut self, handler: H) -> Result<(), TpmDeviceError>

where H: FnMut(&[u8]) -> Vec<u8>,

Serves commands until the peer disconnects.

Each received command frame is passed to handler, whose returned bytes are written back as the response frame. Returns Ok(()) once the peer closes the transport.

Errors

Returns a TpmDeviceError when receiving a command or sending a response fails for any reason other than a clean disconnect.

Trait Implementations

impl Debug for TpmResponder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
