Struct Device 

pub struct Device {
    file: File,
    geometry: Geometry,
}

Open MTD character device.

Access its blocks through Flash.

Fields

file: File

geometry: Geometry

Implementations

impl Device

pub fn open(path: &Path) -> Result<Self, DeviceError>

Opens the MTD character device at path for reading and writing.

Errors

Returns an error if the device can’t be opened or reports a geometry this crate can’t handle.

pub fn open_read_only(path: &Path) -> Result<Self, DeviceError>

Opens the MTD character device at path for reading only.

Errors

Returns an error if the device can’t be opened or reports a geometry this crate can’t handle.

fn open_with(path: &Path, write: bool) -> Result<Self, DeviceError>

Trait Implementations

impl Debug for Device

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

Formats the value using the given formatter.

impl Flash for Device

fn erase(&self, block: u32) -> Result<(), DeviceError>

Erases block.

fn geometry(&self) -> Geometry

Returns the geometry of the flash.

fn is_bad(&self, block: u32) -> Result<bool, DeviceError>

Returns whether block has a bad block marker.

fn mark_bad(&self, block: u32) -> Result<(), DeviceError>

Writes a bad block marker to block.

fn read( &self, block: u32, offset: u32, buf: &mut [u8], ) -> Result<(), DeviceError>

Reads buf.len() bytes from block, starting offset bytes into it.

fn read_unchecked( &self, block: u32, offset: u32, buf: &mut [u8], ) -> Result<(), DeviceError>

Reads like Flash::read, but doesn’t check for ECC errors.

fn write(&self, block: u32, data: &[u8]) -> Result<(), DeviceError>

Writes data from the start of block.
