Struct secgate::util::SimpleBuffer

source ·
pub struct SimpleBuffer { /* private fields */ }
Expand description

A simple buffer to use for transferring bytes between compartments, using shared memory via objects underneath.

Implementations§

source§

impl SimpleBuffer

source

pub fn new(handle: ObjectHandle) -> Self

Build a new SimpleBuffer from an object handle.

source

pub fn max_len(&self) -> usize

Returns the maximum length of a read or write.

source

pub fn handle(&self) -> &ObjectHandle

Get the underlying object handle.

source

pub fn read(&self, buffer: &mut [u8]) -> usize

Read bytes from the SimpleBuffer into buffer, up to the size of the supplied buffer. The actual number of bytes copied is returned.

source

pub fn write(&mut self, buffer: &[u8]) -> usize

Write bytes from buffer into the SimpleBuffer, up to the size of the supplied buffer. The actual number of bytes copied is returned.
