Variants

MsyncArena

Fields

slot: MemSlot

offset: usize

size: usize

Flush the content of a memory mapping to its backing file. slot selects the arena (as returned by Vm::add_mmap_arena). offset is the offset of the mapping to sync within the arena. size is the size of the mapping to sync within the arena.

MadvisePageout

Fields

slot: MemSlot

offset: usize

size: usize

Gives a MADV_PAGEOUT advice to the memory region mapped at slot, with the address range starting at offset from the start of the region, and with size size.

MadviseRemove

Fields

slot: MemSlot

offset: usize

size: usize

Gives a MADV_REMOVE advice to the memory region mapped at slot, with the address range starting at offset from the start of the region, and with size size.

Implementations

impl VmMemoryMappingRequest

pub fn execute(&self, vm: &mut impl Vm) -> VmMemoryMappingResponse

Executes this request on the given Vm.

Arguments

• vm - The Vm to perform the request on.

This does not return a result, instead encapsulating the success or failure in a VmMsyncResponse with the intended purpose of sending the response back over the socket that received this VmMsyncResponse.
