Struct IoBuffer 

pub struct IoBuffer { /* private fields */ }

An unsafe, 'static, partially initialized, and mutable buffer.

It contains full information to describe the buffer.

Implementations

impl IoBuffer

pub unsafe fn new( ptr: *mut MaybeUninit<u8>, len: usize, capacity: usize, ) -> Self

Create a new IoBuffer from a raw pointer, a length, and a capacity.

Safety

The caller must ensure that:

• the pointer is valid for the lifetime of the IoBuffer
• the length is correct (the content can be uninitialized, but must be accessible)
• The capacity should not be smaller than the length.
• the pointer is not used for anything else while the IoBuffer is in use

pub fn as_ptr(&self) -> *mut MaybeUninit<u8>

Get the pointer to the buffer.

pub fn len(&self) -> usize

Get the initialized length of the buffer.

pub fn is_empty(&self) -> bool

Check if the buffer is empty.

pub fn capacity(&self) -> usize

Get the full capacity of the buffer.

Trait Implementations

Converts to this type from the input type.

impl From<IoBuffer> for IoSliceMut

fn from(value: IoBuffer) -> Self
