Struct MockCiDataDevice 

pub struct MockCiDataDevice {
    pub descrambled: VecDeque<Vec<u8>>,
    pub written: Vec<Vec<u8>>,
}

In-memory CiDataDevice for tests and the differential harness.

• descrambled is a scripted queue of TS the “module” returns; each read pops one entry (the “scripted descramble”).
• every byte the host writes is recorded in written, so a test (or a byte-exact comparison against an external reference) can assert the exact scrambled TS that was pushed in.

Fields

descrambled: VecDeque<Vec<u8>>

Scripted descrambled-TS the module returns to the host (FIFO).

written: Vec<Vec<u8>>

Scrambled TS the host wrote, in order.

Implementations

impl MockCiDataDevice

pub fn new(descrambled: impl IntoIterator<Item = Vec<u8>>) -> Self

New mock returning the given descrambled-TS script.

pub fn written_ts(&self) -> Vec<u8>

All scrambled TS the host wrote, concatenated.

Trait Implementations

impl CiDataDevice for MockCiDataDevice

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

Write scrambled TS to the module. ts must be a whole number of TS_PACKET_LEN-byte packets.

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

Read descrambled TS into buf (sized to a multiple of TS_PACKET_LEN); returns the byte count. Ok(0) means none available (non-blocking).

fn poll(&mut self, _timeout: Duration) -> Result<bool>

Wait up to timeout for descrambled TS to become readable; Ok(true) if readable.

impl Debug for MockCiDataDevice

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

Formats the value using the given formatter.

impl Default for MockCiDataDevice

fn default() -> MockCiDataDevice

Returns the “default value” for a type.
