RdmaSnapshotArena

spark_storage::rdma_snapshot

Struct RdmaSnapshotArena 

Source 
pub struct RdmaSnapshotArena;
Expand description

Placeholder when RDMA verbs / CUDA aren’t built. connect always errors, so crate dependents degrade to the host-RAM tier; write/read are unreachable (a stub arena is never successfully constructed).
