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§

source§

impl VmMemoryMappingRequest

source

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.

where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
