Enum VmMemoryMappingRequest

pub enum VmMemoryMappingRequest {
    MsyncArena {
        slot: MemSlot,
        offset: usize,
        size: usize,
    },

}

Variants

MsyncArena

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.

Fields

slot: MemSlot

offset: usize

size: usize

MadvisePageout

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.

Fields

slot: MemSlot

offset: usize

size: usize

MadviseRemove

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.

Fields

slot: MemSlot

offset: usize

size: usize

Implementations

impl VmMemoryMappingRequest

pub fn execute(&self, vm: &dyn 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.
