Struct BlockDev 

pub struct BlockDev { /* private fields */ }

Implementations

impl BlockDev

pub unsafe fn from_file_raw(i: File) -> BlockDev

Treat a file as a block device without checking

Safety

i must refer to a block device file, otherwise the ioctls used by other functions may have undesired effects, including reading and writing memory unexpectedly.

pub fn from_file(i: File) -> Result<BlockDev>

pub fn ro(&self) -> Result<bool>

pub fn block_io_min(&self) -> Result<u32>
