Struct NorMemoryAsync

pub struct NorMemoryAsync<NMS> { /* private fields */ }

Implementations

impl<NMS> NorMemoryAsync<NMS>

Asynchronous NOR flash memory interface from embedded_storage_async::nor_flash.
it is a wrapper around a synchronous NOR flash memory.
Note: all operations are executed synchronously, prentending to be asynchronous.

pub fn new(nor_memory_sync: NMS) -> Self

given a synchronous NOR flash memory, returns an asynchronous NOR flash memory.

pub fn get_sync(self) -> NMS

returns the synchronous NOR flash memory back.

Trait Implementations

impl<NMS> ErrorType for NorMemoryAsync<NMS>

where NMS: ErrorTypeSync,

type Error = <NMS as ErrorType>::Error

Errors returned by this NOR flash.

impl<NMS> NorFlash for NorMemoryAsync<NMS>

where NMS: NorFlashSync,

const WRITE_SIZE: usize = NMS::WRITE_SIZE

The minumum number of bytes the storage peripheral can write

const ERASE_SIZE: usize = NMS::ERASE_SIZE

The minumum number of bytes the storage peripheral can erase

async fn erase(&mut self, from: u32, to: u32) -> Result<(), Self::Error>

Erase the given storage range, clearing all data within [from..to]. The given range will contain all 1s afterwards.

async fn write(&mut self, offset: u32, bytes: &[u8]) -> Result<(), Self::Error>

If power is lost during write, the contents of the written words are undefined, but the rest of the page is guaranteed to be unchanged. It is not allowed to write to the same word twice.

impl<NMS> ReadNorFlash for NorMemoryAsync<NMS>

where NMS: ReadNorFlashSync,

const READ_SIZE: usize = NMS::READ_SIZE

The minumum number of bytes the storage peripheral can read

async fn read( &mut self, address: u32, buf: &mut [u8], ) -> Result<(), Self::Error>

Read a slice of data from the storage peripheral, starting the read operation at the given address offset, and reading bytes.len() bytes.

fn capacity(&self) -> usize

The capacity of the peripheral in bytes.

impl<NMS> MultiwriteNorFlash for NorMemoryAsync<NMS>

where NMS: MultiwriteNorFlashSync,
