Struct CffiRmw 

Source 
pub struct CffiRmw;
Expand description

RMW factory for the C function table backend.

Implementations§

Source§

impl CffiRmw

Source

pub fn open_with_rmw( rmw_name: &str, config: &RmwConfig<'_>, ) -> Result<CffiSession, TransportError>

Phase 104.C.1 — open a session against a named backend. rmw_name selects an entry from the registry populated by nros_rmw_cffi_register_named (Phase 104.B.2).

fn factory() -> R

Construct a fresh factory instance. Called inside the open trampoline. Equivalent to R::default() for backends that derive(Default); the indirection keeps the door open for future per-backend registration knobs.

fn open( self, config: &RmwConfig<'_>, ) -> Result<<R as RustBackend>::Session, TransportError>

Move the factory into a session per the Rmw::open contract.
