Struct EspWlPartition 

pub struct EspWlPartition<T> { /* private fields */ }

Represents a partition wrapped with the ESP-IDF Wear-Leveling algorithm

Implementations

impl<T> EspWlPartition<T>

where T: BorrowMut<EspPartition>,

pub fn new(partition: T) -> Result<Self, EspError>

Wrap the provided raw partition with the ESP-IDF Wear-Leveling algorithm

Return an error if the wrap operation failed, or the WL partition if the operation succeeded.

Arguments:

• partition: The partition to mount

pub fn size(&self) -> usize

Return the size of the mounted WL partition

pub fn sector_size(&self) -> usize

Return the size of a sector in the mounted WL partition

pub fn read(&mut self, offset: usize, buf: &mut [u8]) -> Result<(), EspError>

Read data from the mounted WL partition

Arguments

• offset: The offset in the partition to read from, in bytes
• buf: The buffer to read the data into

Return an error if the read operation failed. The read operation would fail if the offset and buffer length are beyond the partition bounds.

The read operation will also fail if the offset and the buffer length are not aligned with the partition read alignment.

pub fn write(&mut self, offset: usize, data: &[u8]) -> Result<(), EspError>

Write data to the mounted WL partition

Arguments

• offset: The offset in the partition to write to, in bytes
• data: The data to write to the partition

Return an error if the write operation failed. The write operation would fail if the offset and data length are beyond the partition bounds.

The write operation will also fail if the offset and the data length are not aligned with the partition write alignment.

pub fn erase(&mut self, offset: usize, size: usize) -> Result<(), EspError>

Erase a region of the mounted WL partition

Arguments

• offset: The offset in the partition to start erasing from, in bytes
• size: The size of the region to erase, in bytes

Return an error if the erase operation failed. The erase operation would fail if the offset and size are beyond the partition bounds.

Trait Implementations

impl<T> Drop for EspWlPartition<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<T> RawHandle for EspWlPartition<T>

type Handle = i32

fn handle(&self) -> Self::Handle

Care should be taken to use the returned ESP-IDF driver raw handle only while the driver is still alive, so as to avoid use-after-free errors.

impl<T> Send for EspWlPartition<T>

where T: Send,
