Struct kvm_rs::UserMem [−][src]
Wrapper to safely allocate memory for guest VMs.
The underlying memory is freed automatically once the UserMem instance is dropped.
Memory can be mapped into a guest VM with
Vm::set_user_memory_region.
Implementations
impl UserMem[src]
pub fn new(len: usize) -> Result<UserMem>[src]
Allocate a zero-initialized memory region of len bytes.
pub fn with_init(len: usize, init_from: &[u8]) -> Result<UserMem>[src]
Allocate a zero-initialized memory region of len bytes and initialize the first bytes
with init_from.
Panics
Panics if init_from is larger than the memory size len.
pub fn load(&mut self, addr: PhysAddr, data: &[u8])[src]
Load the bytes stored in data into memory at physical address addr.
Panics
Panics if addr + data.len is larger than the memory size len.
