pub struct MemoryState { /* private fields */ }

Memory state management

Implementations

impl MemoryState

pub fn new() -> Self

Create a new memory state

pub fn with_limit(max_memory_usage: usize) -> Self

Create a new memory state with memory limit

Arguments

• max_memory_usage - Maximum allowed memory usage in bytes

pub fn read_memory(&self, address: u64, size: usize) -> JitResult<Vec<u8>>

Read memory from a specific address

Arguments

• address - Starting address to read from
• size - Number of bytes to read

Returns

A vector containing the memory contents (uninitialized memory returns 0)

pub fn write_memory(&mut self, address: u64, data: &[u8]) -> JitResult<()>

Write memory to a specific address

Arguments

• address - Starting address to write to
• data - Data to write

pub fn allocate_region( &mut self, address: u64, size: usize, label: Option<String>, ) -> JitResult<u64>

Allocate a memory region

Arguments

• address - Starting address of the region
• size - Size of the region in bytes
• label - Optional label for the region

Returns

The allocation ID

pub fn deallocate_region(&mut self, allocation_id: u64) -> JitResult<()>

Deallocate a memory region

Arguments

• allocation_id - The ID of the allocation to free

pub fn get_allocated_regions(&self) -> Vec<&MemoryRegion>

Get information about all allocated regions

pub fn find_region_containing(&self, address: u64) -> Option<&MemoryRegion>

Find the region containing a specific address

Arguments

• address - The address to search for

Returns

Information about the region containing the address, if any

pub fn get_memory_stats(&self) -> MemoryStats

Get memory usage statistics

pub fn clear(&mut self)

Clear all memory and allocations

pub fn read_u32(&self, address: u64) -> JitResult<u32>

Read a specific type from memory

Arguments

• address - Address to read from

Returns

The value read from memory

pub fn read_u64(&self, address: u64) -> JitResult<u64>

Read a u64 from memory

pub fn read_f32(&self, address: u64) -> JitResult<f32>

pub fn write_u64(&mut self, address: u64, value: u64) -> JitResult<()>

Write a u64 to memory

pub fn write_f32(&mut self, address: u64, value: f32) -> JitResult<()>

Write an f32 to memory

pub fn write_f64(&mut self, address: u64, value: f64) -> JitResult<()>

Write an f64 to memory

pub fn set_memory_limit(&mut self, limit: usize)

Set memory limit

pub fn memory_limit(&self) -> usize

Get memory limit
