Struct ExecutableMemory 

pub struct ExecutableMemory { /* private fields */ }

executable memory region for trampolines

automatically freed when dropped

Implementations

impl ExecutableMemory

pub fn allocate_near(target: usize, size: usize) -> Result<Self>

allocate executable memory near a target address

tries to allocate within ±2GB of target for relative jumps. falls back to any available address if near allocation fails.

pub fn allocate(size: usize) -> Result<Self>

allocate executable memory at any available address

pub fn base(&self) -> usize

get base address

pub fn size(&self) -> usize

get total allocated size

pub fn used(&self) -> usize

get used bytes

pub fn available(&self) -> usize

get available bytes

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

write code to the memory region

returns the address where the code was written

pub fn ptr_at(&self, offset: usize) -> *mut u8

get pointer at offset

pub fn read_at(&self, offset: usize, len: usize) -> Result<&[u8]>

read bytes from offset

pub fn contains(&self, addr: usize) -> bool

check if an address is within this memory region

pub fn is_near(&self, target: usize) -> bool

check if this memory is within rel32 range of target

pub fn flush_icache(&self) -> Result<()>

flush instruction cache for this region

pub fn leak(self) -> *mut u8

take ownership without freeing
