rdma_io::mr

Struct OwnedMemoryRegion 

Source 
pub struct OwnedMemoryRegion { /* private fields */ }
Expand description

An owned memory region.

The buffer is owned by this struct and deregistered + freed on drop.

Implementations§

Source§

impl OwnedMemoryRegion

Source

pub fn lkey(&self) -> u32

The local key.

Source

pub fn rkey(&self) -> u32

The remote key.

Source

pub fn addr(&self) -> u64

The registered address as a u64 (for WR construction).

Source

pub fn as_slice(&self) -> &[u8] ⓘ

Access the registered buffer.

Source

pub fn as_mut_slice(&mut self) -> &mut [u8] ⓘ

Mutably access the registered buffer.

Source

pub fn as_raw(&self) -> *mut ibv_mr

Raw pointer (for advanced/FFI use).

Source

pub fn to_remote(&self) -> RemoteMr

Create a RemoteMr descriptor from this MR’s remote key and address.

The returned descriptor can be sent to a remote peer for one-sided operations.
