Struct dynasmrt::components::MemoryManager

pub struct MemoryManager { /* fields omitted */ }

This struct implements a protection-swapping assembling buffer

Implementations

impl MemoryManager

pub fn new(initial_mmap_size: usize) -> Result<Self>

Create a new memory manager, with initial_mmap_size data allocated

pub fn committed(&self) -> usize

Returns the amount of bytes already committed to the manager

pub fn execbuffer_addr(&self) -> usize

Returns the current start address of the managed executable memory

pub fn commit<F>(&mut self, new: &mut Vec<u8>, f: F) where
    F: FnOnce(&mut [u8], usize, usize), 

Commits the data from new into the managed memory, calling f when the buffer is moved to fix anything that relies on the address of the buffer

pub fn write(&self) -> RwLockWriteGuard<'_, ExecutableBuffer>

Borrow the internal memory buffer mutably

pub fn finalize(self) -> Result<ExecutableBuffer, Self>

finalizes the currently committed part of the buffer.

pub fn reader(&self) -> Arc<RwLock<ExecutableBuffer>>

Create an atomically refcounted reference to the internal executable buffer

impl Debug for MemoryManager

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

Formats the value using the given formatter.
