Function rdp::simplify_rdp_ffi

#[no_mangle]pub extern "C" fn simplify_rdp_ffi(coords: Array, precision: c_double) -> Array

FFI wrapper for RDP, returning simplified geometry coordinates

Callers must pass two arguments:

• a Struct with two fields:
  • data, a void pointer to an array of floating-point point coordinates: [[1.0, 2.0], ...]
  • len, the length of the array being passed. Its type must be size_t
• a double-precision float for the tolerance

Implementations calling this function must call drop_float_array with the returned Array pointer, in order to free the memory it allocates.

Safety

This function is unsafe because it accesses a raw pointer which could contain arbitrary data
