Struct nrf_softdevice::Flash

pub struct Flash { /* private fields */ }

Singleton instance of the Flash softdevice functionality.

Implementations

impl Flash

pub fn take(_sd: &Softdevice) -> Flash

Takes the Flash instance from the softdevice.

Panics

Panics if called more than once.

Trait Implementations

impl AsyncNorFlash for Flash

const WRITE_SIZE: usize = 4usize

The minumum number of bytes the storage peripheral can write

const ERASE_SIZE: usize = 4_096usize

The minumum number of bytes the storage peripheral can erase

type WriteFuture<'a> = impl Future<Output = Result<(), FlashError>> + 'a

fn write<'a>(&'a mut self, offset: u32, data: &'a [u8]) -> Self::WriteFuture<'a>

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.

type EraseFuture<'a> = impl Future<Output = Result<(), FlashError>> + 'a

fn erase<'a>(&'a mut self, from: u32, to: u32) -> Self::EraseFuture<'a>

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

impl AsyncReadNorFlash for Flash

const READ_SIZE: usize = 1usize

The minumum number of bytes the storage peripheral can read

type ReadFuture<'a> = impl Future<Output = Result<(), FlashError>> + 'a

fn read<'a>(
&'a mut self,
address: u32,
data: &'a mut [u8]
) -> Self::ReadFuture<'a>

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 ErrorType for Flash

type Error = FlashError

Errors returned by this NOR flash.

impl ReadNorFlash for Flash

const READ_SIZE: usize = 1usize

The minumum number of bytes the storage peripheral can read

fn read(&mut self, address: u32, data: &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.
