Struct RustBackendAdapter 

pub struct RustBackendAdapter<R>(/* private fields */);

Wraps a Rust Rmw backend behind the canonical NrosRmwVtable C ABI. See module docs.

Implementations

impl<R: RustBackend> RustBackendAdapter<R>

pub const VTABLE: NrosRmwVtable

Monomorphised vtable for backend R. The const is promoted to per-type static storage, so &Self::VTABLE has 'static lifetime — safe to hand to nros_rmw_cffi_register.

pub fn register() -> NrosRmwRet

Install the per-R vtable into the cffi registry under the implicit name "default". Idempotent — re-registering the same vtable is a no-op from the runtime’s perspective.

Most backends should use register_named instead so they show up in the registry under their canonical name ("zenoh", "dds", "xrce", …). Phase 128.B.5 routes the implicit-name path through _register_named too, so the legacy unnamed C shim no longer participates in registration.

pub unsafe fn register_named(name: *const c_char) -> NrosRmwRet

Phase 104.B.2 — install the per-R vtable under a stable name. Multiple backends can coexist via this entry point.

Safety

name must be a valid NUL-terminated UTF-8 string.
