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]

`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.

+
