Allocates and deallocates inner VM’s memory pages and handles page faults.

Implementations

impl<I: InnerVm> MemoryManager<I>

pub fn new<O: OuterVm>( inner_vm: I, outer_vm: &mut O, program: ProgramData, heap_pages: RangeSet, resident_pages: RangeSet, export_count: usize, auth_output_len: usize, ) -> Result<Self, ApiError>

pub fn alloc(&mut self, size: u64) -> Option<(u64, u64)>

pub fn dealloc(&mut self, address: u64, size: u64) -> Result<(), ApiError>

pub fn touch(&mut self, address: u64) -> Result<(), PageFaultError>

Handle page fault at the specified address.

pub fn append_output( &mut self, stream: OutputStream, inner_src: u64, len: u64, ) -> Result<(), AppendOutputError>

Append data to the guest program’s output stream.

pub fn export<O: OuterVm>( &mut self, outer_vm: &mut O, ) -> Result<(RangeSet, RangeSet, VecMap<u64, Hash>, VecMap<u64, Hash>, u32, [u32; 4]), ApiError>

Exports the modified pages as segments.
