Struct CounterView 

pub struct CounterView<F, M>
where
    F: MultiwriteNorFlash + 'static,
    M: RawMutex + 'static,
{ /* private fields */ }

View implementing [umsh_hal::CounterStore] on top of a shared FlashStore. Counters are stored as little-endian u32 values keyed by the caller-supplied context bytes (the MAC layer is expected to prefix them with mac.tx: / mac.rx:).

Implementations

impl<F, M> CounterView<F, M>

where F: MultiwriteNorFlash + 'static, M: RawMutex + 'static,

pub fn new(storage: &'static FlashStore<F, M>) -> Self

Construct a counter view over the shared static storage.

Trait Implementations

impl<F, M> CounterStore for CounterView<F, M>

where F: MultiwriteNorFlash + 'static, M: RawMutex + 'static,

type Error = Error<<F as ErrorType>::Error>

async fn load(&self, context: &[u8]) -> Result<u32, Self::Error>

Load the stored counter for context, or 0 if missing.

async fn store(&self, context: &[u8], value: u32) -> Result<(), Self::Error>

Persist a counter value for context.

async fn flush(&self) -> Result<(), Self::Error>

Flush any buffered state to durable storage.
