Struct InOutBuf 

pub struct InOutBuf<'inp, 'out, T> { /* private fields */ }

A lightweight I/O buffer abstraction without depending on the RustCrypto inout crate.

Implementations

impl<'inp, 'out, T> InOutBuf<'inp, 'out, T>

pub fn new( in_buf: &'inp [T], out_buf: &'out mut [T], ) -> Result<Self, NotEqualError>

Create an in/out buffer from separate input and output slices.

pub unsafe fn from_raw(in_ptr: *const T, out_ptr: *mut T, len: usize) -> Self

Construct from raw pointers.

pub fn get_in(&self) -> &[T]

Access the input side without copying.

pub fn get_out(&mut self) -> &mut [T]

Access the output side without copying.

pub fn into_out(self) -> &'out mut [T]

Return the output slice while preserving the caller’s write access.

pub fn into_out_with_copied_in(self) -> &'out mut [T]

where T: Copy,

Return the output slice, copying input into output when the regions differ.

pub fn into_raw(self) -> (*const T, *mut T)

Consume the buffer and return the raw pointers.

pub fn len(&self) -> usize

Length of the buffer.

pub fn is_empty(&self) -> bool

Whether the buffer is empty.

Trait Implementations

impl<'a, T> From<&'a mut [T]> for InOutBuf<'a, 'a, T>

fn from(buf: &'a mut [T]) -> Self

Converts to this type from the input type.
