Struct dynasmrt::mmap::MutableBuffer

pub struct MutableBuffer { /* fields omitted */ }

ExecutableBuffer equivalent that holds a buffer of mutable memory instead of executable memory. It also derefs to a &mut [u8]. This structure does not allocate when its size is 0.

Implementations

impl MutableBuffer

pub fn new(size: usize) -> Result<MutableBuffer>

Create a new mutable buffer, backed by a buffer of size size. It will start with an initialized length of 0.

pub fn size(&self) -> usize

Query the backing size of this mutable buffer

pub fn set_len(&mut self, length: usize)

Set the length of the usable part of this mutable buffer. The length should not be set larger than the allocated size, otherwise methods can panic.

pub fn make_exec(self) -> Result<ExecutableBuffer>

Change this mutable buffer into an executable buffer.

Trait Implementations

impl Debug for MutableBuffer

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

Formats the value using the given formatter.

impl Default for MutableBuffer

fn default() -> MutableBuffer

Returns the “default value” for a type.

impl Deref for MutableBuffer

type Target = [u8]

The resulting type after dereferencing.

fn deref(&self) -> &[u8]

Dereferences the value.

impl DerefMut for MutableBuffer

fn deref_mut(&mut self) -> &mut [u8]

Mutably dereferences the value.
