Enum BackendResolution 

Source 
pub enum BackendResolution {
    Single(&'static NrosRmwVtable),
    NoBackend,
    Ambiguous,
    Unknown,
}
Expand description

Phase 128.A.3 — outcome of resolve_backend.

Variants§

§

Single(&'static NrosRmwVtable)

Exactly one matching backend; use its vtable.

§

NoBackend

No backend linked into the binary. Maps to NROS_RMW_RET_NO_BACKEND.

§

Ambiguous

More than one backend linked and no selector given. Maps to NROS_RMW_RET_AMBIGUOUS_BACKEND.

§

Unknown

Selector did not match any registered backend. Maps to NROS_RMW_RET_UNKNOWN_BACKEND.
