Struct MockTransport 

pub struct MockTransport { /* private fields */ }

Mock transport for testing. Programs expected command/response exchanges.

Implementations

impl MockTransport

pub const fn new() -> Self

Create a new empty mock transport with no expected exchanges.

pub fn expect(&mut self, command: &[u8], response: &[u8])

Queue an expected command/response exchange.

When write() is called with command, the corresponding response will be returned by the next read().

pub fn from_fixture(path: &Path) -> Result<Self, Error>

Load expected exchanges from a fixture file.

The file format uses > prefixed lines for commands and < prefixed lines for responses. Literal \r sequences are converted to 0x0D.

Errors

Returns an error if the file cannot be read.

pub fn queue_read(&mut self, data: &[u8])

Queue data to be returned by the next read() without requiring a preceding write().

This is useful for testing unsolicited incoming data (e.g., MMDVM frames received from the radio without a prior command).

pub const fn expect_any_write(&mut self)

Accept any subsequent write() calls without validation.

When enabled, writes succeed without checking against expected exchanges and no response is queued.

pub fn assert_complete(&self)

Panic if any expected exchanges remain unconsumed.

Panics

Panics if there are remaining exchanges that were not exercised.

Trait Implementations

impl Debug for MockTransport

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

Formats the value using the given formatter.

impl Default for MockTransport

fn default() -> Self

Returns the “default value” for a type.

impl Transport for MockTransport

async fn write(&mut self, data: &[u8]) -> Result<(), TransportError>

Send raw bytes to the radio.

async fn read(&mut self, buf: &mut [u8]) -> Result<usize, TransportError>

Read available bytes into buffer, return count of bytes read.

async fn close(&mut self) -> Result<(), TransportError>

Close the connection.

fn set_baud_rate(&mut self, _baud: u32) -> Result<(), TransportError>

Change the transport baud rate.
