Type Definition libceed_sys::bind_ceed::CeedQFunctionUser

type CeedQFunctionUser = Option<unsafe extern "C" fn(ctx: *mut c_void, Q: CeedInt, in_: *const *const CeedScalar, out: *const *mut CeedScalar) -> c_int>;

Handle for the object describing the user CeedQFunction

@param ctx user-defined context set using CeedQFunctionSetContext() or NULL

@param Q number of quadrature points at which to evaluate

@param in array of pointers to each input argument in the order provided by the user in CeedQFunctionAddInput(). Each array has shape [dim, num_comp, Q] where dim is the geometric dimension for \ref CEED_EVAL_GRAD (dim=1 for \ref CEED_EVAL_INTERP) and num_comp is the number of field components (num_comp=1 for scalar fields). This results in indexing the ith input at quadrature point j as in[i][(d*num_comp + c)*Q + j].

@param out array of pointers to each output array in the order provided using CeedQFunctionAddOutput(). The shapes are as above for \a in.

@return An error code: 0 - success, otherwise - failure
