Struct KeyValueView 

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

View implementing [umsh_hal::KeyValueStore] on top of a shared FlashStore. The view itself is essentially a thin pointer; the real storage lives in the static FlashStore.

Implementations

impl<F, M> KeyValueView<F, M>

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

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

Construct a KV view over the shared static storage.

Trait Implementations

impl<F, M> KeyValueStore for KeyValueView<F, M>

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

async fn load( &self, key: &[u8], buf: &mut [u8], ) -> Result<Option<usize>, Self::Error>

Load a value into buf, returning the stored length when present.

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

Store a value for key.

async fn delete(&self, key: &[u8]) -> Result<(), Self::Error>

Delete any stored value for key.
