Struct MemoryRegion

pub struct MemoryRegion {
    pub remote_addr: u64,
    pub rkey: u32,
    pub len: usize,
}

Expand description

A registered memory region exposed for one-sided (RDMA) reads.

When exposed_region returns Some(MemoryRegion), the receiving side may read len bytes starting at remote_addr using RDMA with the provided rkey. No CPU involvement on the target shard is required.

When RDMA hardware or software support is absent, exposed_region returns None and callers must fall back to standard RPC-based access.

Fields§

§remote_addr: u64

Remote virtual address of the pinned region.

§rkey: u32

RDMA remote key authorizing reads of this region.

§len: usize

Length of the region in bytes.
