Struct MemoryRegion 

Source 
pub struct MemoryRegion {
    pub guest_addr: GuestAddress,
    pub size: u64,
    pub host_addr: Option<*mut u8>,
    pub read_only: bool,
}
Expand description

Fields§

§guest_addr: GuestAddress

Guest physical address of the region start.

§size: u64

Size of the region in bytes.

§host_addr: Option<*mut u8>

Host virtual address (if mapped).

§read_only: bool

Whether the region is read-only.
