Expand description

A page-aligned buffer used to double-buffer IO data.

Implementations§

Source§

impl BounceBuffer

Source

pub fn new(size: usize) -> Self

Allocates a new bounce buffer of size bytes.

Source

pub fn as_mut_bytes(&mut self) -> &mut [u8] ⓘ

Returns the bounce buffer memory.

Source

pub fn io_vecs(&self) -> &[IoBuffer<'_>]

Returns a reference to the underlying buffer.

This is returned in a form convenient for using with IO functions.
