Module ffi 

Raw FFI bindings to the ASSIST C library.

assist_ephem and assist_extras are treated as opaque types. Field access goes through thin C helpers compiled in helpers.c. REBOUND types (reb_simulation, reb_particle) come from librebound_sys::ffi and are re-exported here so ASSIST FFI signatures resolve transparently.

Structs

assist_ephem

Opaque ASSIST ephemeris data.

assist_extras

Opaque ASSIST extras (attaches ASSIST forces to a REBOUND simulation).

reb_particle

REBOUND particle: position, velocity, acceleration, mass, radius, hash.

reb_simulation

Opaque REBOUND simulation.
