Struct rmw_session_t 

#[repr(C)]
pub struct rmw_session_t {
    pub node_name: *const c_char,
    pub namespace_: *const c_char,
    pub _reserved: [u8; 8],
    pub backend_data: *mut c_void,
}

Per-process RMW session — the entity returned by vtable->create_session.

Carries the node identity (used for diagnostics + wire-level topic-key derivation in some backends) plus the opaque backend-private state.

The 8-byte _reserved slot is sized for a forthcoming vtable: const struct nros_rmw_vtable_t * field that Phase 104’s multi-instance work will land here. Backends and runtime keep these bytes zero.

Fields

node_name: *const c_char

Node name (borrowed from caller; outlives the session).

namespace_: *const c_char

Node namespace (borrowed from caller; outlives the session).

_reserved: [u8; 8]

Reserved for future fields (Phase 104 vtable pointer slot); must be zero.

backend_data: *mut c_void

Opaque backend state. NULL for an uninitialised session.
