pub fn new() -> FlashStorage

Trait Implementations

impl Debug for FlashStorage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FlashStorage

fn default() -> Self

Returns the “default value” for a type.

impl ReadStorage for FlashStorage

fn capacity(&self) -> usize

The SPI flash size is configured by writing a field in the software bootloader image header. This is done during flashing in espflash / esptool.

type Error = FlashStorageError

An enumeration of storage errors

fn read(&mut self, offset: u32, bytes: &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.

impl Storage for FlashStorage

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

Write a slice of data to the storage peripheral, starting the write operation at the given address offset (between 0 and self.capacity()).
