Struct kvm_rs::UserMem [−][src]
pub struct UserMem { /* fields omitted */ }
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]
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
.
