Implementations

impl MemoryMap

pub const fn empty() -> MemoryMap

Creates an empty memory map.

pub fn new( page_size: u32, ro_data_size: u32, rw_data_size: u32, stack_size: u32, ) -> Result<MemoryMap, &'static str>

Calculates the memory map from the given parameters.

pub fn page_size(&self) -> u32

The page size of the program.

pub fn heap_base(&self) -> u32

The address at which the program’s heap starts.

pub fn max_heap_size(&self) -> u32

The maximum size of the program’s heap.

pub fn ro_data_address(&self) -> u32

The address at where the program’s read-only data starts inside of the VM.

pub fn ro_data_size(&self) -> u32
