Trait implemented by synchronous block devices used by MscClass.

Required Associated Types

type Error

Error type returned by storage operations.

Required Methods

fn block_size(&self) -> u32

Returns the block size in bytes.

fn block_count(&self) -> u32

Returns the total amount of logical blocks.

fn read_blocks(&mut self, lba: u32, buf: &mut [u8]) -> Result<(), Self::Error>

Reads consecutive logical blocks starting at lba into buf.

buf.len() is a non-zero multiple of self.block_size().

fn write_blocks(&mut self, lba: u32, data: &[u8]) -> Result<(), Self::Error>

Writes consecutive logical blocks starting at lba from data.

data.len() is a non-zero multiple of self.block_size().

fn flush(&mut self) -> Result<(), Self::Error>

Flushes pending writes to backing storage.

Provided Methods

fn is_write_protected(&self) -> bool

Returns whether the media is write-protected.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
