Struct NoStore 

pub struct NoStore;

A no-op store that rejects all writes. Used when DTN is disabled (paired with AlwaysReachable).

Trait Implementations

impl MessageStore for NoStore

fn write( &mut self, _target: Address, _data: &[u8], _ttl_secs: u16, _created_at_secs: u32, ) -> StoreResult

Persist a message for later delivery.

fn read(&mut self, _target: Address, _buf: &mut [u8]) -> Option<usize>

Read and remove the oldest stored message for target. Copies the message into buf and returns its length. Returns None if nothing is stored for that target.

fn peek_size(&self, _target: Address) -> Option<usize>

Returns the byte length of the next message for target without removing it. Used by the driver to check if the message fits in the SRSPP buffer before reading.

fn pending_targets(&self) -> u16

Bitmap of targets that have pending messages. Bit N set = ground station N has at least one stored message.

fn expire(&mut self, _now_secs: u32)

Discard all messages whose TTL has expired. now_secs uses the same epoch as created_at_secs.
