Methods

impl<'a> AppFlash<'a>

pub fn new(
    driver: &'a NonvolatileStorage,

) -> AppFlash<'a>

fn enqueue_write(&self, flash_address: usize, appid: AppId) -> ReturnCode

Trait Implementations

impl<'a> NonvolatileStorageClient for AppFlash<'a>

fn read_done(&self, _buffer: &'static mut [u8], _length: usize)

read_done is called when the implementor is finished reading in to the buffer. The callback returns the buffer and the number of bytes that were actually read.

fn write_done(&self, buffer: &'static mut [u8], _length: usize)

write_done is called when the implementor is finished writing from the buffer. The callback returns the buffer and the number of bytes that were actually written.

impl<'a> Driver for AppFlash<'a>

fn allow(
    &self,
    appid: AppId,
    allow_num: usize,
    slice: AppSlice<Shared, u8>
) -> ReturnCode

Setup buffer to write from.

allow_num

• 0: Set write buffer. This entire buffer will be written to flash.

fn subscribe(&self, subscribe_num: usize, callback: Callback) -> ReturnCode

Setup callbacks.

subscribe_num

• 0: Set a write_done callback.

fn command(
    &self,
    command_num: usize,
    arg1: usize,
    _: usize,
    appid: AppId
) -> ReturnCode

App flash control.

command_num

• 0: Driver check.
• 1: Write the memory from the allow buffer to the address in flash.
