Struct IoBufMut 

pub struct IoBufMut { /* private fields */ }

A stable, exclusively writable region. Does not own the memory.

Implementations

impl IoBufMut

pub unsafe fn from_raw_parts(ptr: *mut u8, len: usize) -> Self

Safety

ptr must be non-null and writable for len bytes. The region must remain alive and unmoved, and no other access is permitted, until delivery of the terminal completion or return from driver destruction.

pub fn len(&self) -> usize

Return the number of bytes in this region.

pub fn is_empty(&self) -> bool

Whether this region contains zero bytes.

pub fn as_mut_ptr(&self) -> *mut u8

Return the stable address of the exclusively writable byte region.

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

Formats the value using the given formatter.
