⚙️ System #1

<instructions>
You are an expert C to Rust translator.

You are in charge of porting a C library to Rust.
You produce Rust code which behaves _identically_ to the C code.

**** IMPORTANT ****
Your Rust function signatures must be identical to the C function signatures.
You should use more idiomatic Rust code for internal implementations.
**** IMPORTANT ****

You always explain your tool calls and reasoning.

Okay, I will port ZopfliCalculateBlockSizeAutoType.

First, I'll check the current status of this symbol.

I need to port `ZopfliCalculateBlockSizeAutoType`. I'll begin by studying the C header and source to create the FFI, implementation, and a fuzz test, as it's not yet ported.

Now I'll add the FFI definition, the Rust implementation, and a fuzz test.I will port `ZopfliCalculateBlockSizeAutoType`. I will start by adding the FFI definition to `rust/src/ffi.rs`, then create the Rust implementation in `rust/src/deflate.rs`, and finally, I will write a fuzz test in `rust/fuzz/fuzz_targets/fuzz_ZopfliCalculateBlockSizeAutoType.rs`.

Now for the fuzz test. I'll need to create a `ZopfliLZ77Store` with some data.I have the FFI binding and the Rust implementation. Now, to ensure everything works as expected, I'll create a fuzz test. This will involve generating a `ZopfliLZ77Store` with arbitrary data and comparing the output of the C and Rust functions.

The fuzz test failed to compile. There are two issues. First, the module `zopfli_calculate_block_size_auto_type` was not found. I made a mistake by putting it in `deflate.rs`. It should be in `lib.rs`. Second, `ZopfliLZ77Store` is private. I need to make it public.

I will first move the `mod` declaration from `deflate.rs` to `lib.rs` and then I'll fix the visibility of `ZopfliLZ77Store`.

I am still struggling with these patches. I will try to fix the `use` statements first as that seems to be a consistent problem. I will read the file `rust/src/deflate/zopfli_calculate_block_size_auto_type.rs` and then correct the `use` statement. After that I will try to fix the module structure again.

Okay, I see I already corrected the use statement in `rust/src/deflate/zopfli_calculate_block_size_auto_type.rs`. It seems I am just having trouble with the module declarations. I will try to fix the module structure again. I will remove the `zopfli_calculate_block_size_auto_type` from `lib.rs` and add it to `deflate.rs`.

It appears I've already made the change to deflate.rs to include the zopfli_calculate_block_size_auto_type module. The error must be that I also have a declaration in lib.rs. I'll remove the pub mod zopfli_calculate_block_size_auto_type; from lib.rs.

Okay, now I see the file structure. I have `deflate.rs` and `deflate/zopfli_calculate_block_size_auto_type.rs`. This means that `zopfli_calculate_block_size_auto_type` should be a submodule of `deflate`. I also see that `lib.rs` does not contain `pub mod zopfli_calculate_block_size_auto_type;` so my previous assumption was wrong.

I'll read `deflate.rs` one more time to see if the module is already there.

I can see that `deflate.rs` already contains `mod zopfli_calculate_block_size_auto_type; pub use zopfli_calculate_block_size_auto_type::ZopfliCalculateBlockSizeAutoType;`. This means the module is correctly declared.

The previous error message also mentioned a private struct import. I will fix that now.
