The header file 'operator_typers.h' does not provide the specific definitions for the 'Input' and 'Output' structures.

The header file 'operator_typers.h' does not provide the specific definitions for the 'Input' and 'Output' structures.

/** */
typedef struct Input Input_t;

/** */
typedef struct Output Output_t;

I think it should be this:

/** */
typedef struct Input{
Vec_uint8_t id;
Vec_uint8_t data;
} Input_t;

/** */
typedef struct Output{
Vec_uint8_t id;
Vec_uint8_t data;
} Output_t;

Input and Output are defined as opaque type in C++. You can find there definition in:
input

dora/apis/rust/operator/types/src/lib.rs

Lines 77 to 86 in 06a7d0b

	#[derive_ReprC]
	#[repr(opaque)]
	#[derive(Debug)]
	pub struct Input {
	pub id: safer_ffi::String,
	pub data_array: Option<FFI_ArrowArray>,
	pub schema: FFI_ArrowSchema,
	pub metadata: Metadata,
	}

output

dora/apis/rust/operator/types/src/lib.rs

Lines 103 to 112 in 06a7d0b

	#[derive_ReprC]
	#[repr(opaque)]
	#[derive(Debug)]
	pub struct Output {
	pub id: safer_ffi::String,
	pub data_array: FFI_ArrowArray,
	pub schema: FFI_ArrowSchema,
	pub metadata: Metadata,
	}

This is this way as some of the types are Rust types

@ShoreFlower To access the id and data of inputs, you can use the dora_read_input_id and dora_read_data functions.
