Struct sunrise_libuser::types::MappedSharedMemory

pub struct MappedSharedMemory {
    handle: SharedMemory,
    addr: usize,
    size: usize,
    perm: MemoryPermissions,
}

A mapping to a shared memory region.

When dropped, the memory region will be unmapped, and the SharedMemory handle associated with it will be closed.

Fields

handle: SharedMemory

addr: usize

size: usize

perm: MemoryPermissions

Implementations

impl MappedSharedMemory

pub fn as_ptr(&self) -> *const u8

Gets a raw pointer to the underlying shared memory.

The pointer is valid until the MappedSharedMemory instance gets dropped.

pub fn as_mut_ptr(&self) -> *mut u8

Gets a mutable raw pointer to the underlying shared memory.

The pointer is valid until the MappedSharedMemory instance gets dropped.

pub fn len(&self) -> usize

Gets the byte length of the mapped shared memory.

pub fn as_shared_mem(&self) -> &SharedMemory

Return a reference to the underlying shared memory. Useful to send a copy of the handle of an already mapped shared memory via IPC.
