Struct InMemoryHotplugBackend 

pub struct InMemoryHotplugBackend {
    pub calls: Mutex<Vec<(bool, u64, u64)>>,
}

Test backend that records plug / unplug calls without doing any host mmap work. Useful for unit tests; production code wires HvfVm.

Fields

calls: Mutex<Vec<(bool, u64, u64)>>

Calls in order: (true, base, len) for plug, (false, base, len) for unplug.

Trait Implementations

impl Debug for InMemoryHotplugBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InMemoryHotplugBackend

fn default() -> InMemoryHotplugBackend

Returns the “default value” for a type.

impl MemHotplugBackend for InMemoryHotplugBackend

fn plug(&self, guest_base: u64, len: u64) -> Result<(), String>

Map [guest_base, guest_base + len) into the VM. len is always a multiple of BLOCK_SIZE.

fn unplug(&self, guest_base: u64, len: u64) -> Result<(), String>

Unmap the range [guest_base, guest_base + len).
