Struct SharedMemoryState 

struct SharedMemoryState {
    paddr: usize,
    size: usize,
    capacity: usize,
    permissions: usize,
    valid: bool,
    mapping_count: usize,

}

Internal state of a shared memory object

Fields

paddr: usize

Physical address of the shared memory region

size: usize

Size of the shared memory region in bytes

capacity: usize

Allocated capacity of the shared memory region in bytes

permissions: usize

Access permissions for the shared memory

valid: bool

Whether this shared memory is still valid

mapping_count: usize

Number of active mappings

stale_pages: Vec<(usize, usize)>

Old allocations kept alive while mappings still exist

owns_memory: bool

Whether this object owns the physical memory (should free on drop)

Implementations

impl SharedMemoryState

fn new(paddr: usize, size: usize, permissions: usize, owns_memory: bool) -> Self
