Likewise here, no need to unwrap and then re-wrap the struct, just use the kernel one

We don't need the ScanFile type defined here anymore. Since the kernel now has a similar struct, just use that one.
Same comment for all the other custom ScanFile defs.

Yeah makes sense, looks pretty clean now imo

I went down the lifetime rabbithole to see if i could keep it as &str and it ended up being really complicated and doubtful it makes a difference perf wise.

Yeah, we were copying it anyway before, just one layer lower

It's already a string

This doesn't work at all. See test failures.
In particular:
- import
ScanFile - You can't create a string slice from a
String, so you need something like:
let path = file.path.as_str();
(context.callback)(
context.engine_context,
kernel_string_slice!(path),
file.size,
stats.as_ref(),
&file.dv_info,
&partition_map,
);There was a problem hiding this comment.
Yeah makes sense, fixed. Is there to run these tests locally? I took a look at the GH action but seems like a non-trivial amount of setup.

I think you should be able to just run cargo test in the ffi crate locally

I'm also not seeing a fix? I think you might need to push
This PR addresses #547 by consolidating individual parameters to use ScanFile.
What changes are proposed in this pull request?
Changes:
Introduced ScanFile struct in state.rs to consolidate callback parameters
Updated ScanCallback type signature to use the new struct
Modified callback implementations across codebase
Updated tests and examples to use new struct-based approach
How was this change tested?
Validated via:
cargo test --all-features --all-targets -- --skip read_table_version_hdfsThis is a pure refactor so no new tests need to be written. Skipped the
read_table_version_hdfsbecause of a Java dependency issue I ran into. Saw that we did this in some other places, so seems ok.This PR affects the following public APIs
Simplifies the code base by wrapping all the call sites in a single ScanFile definition.
Additional Context
This PR was entirely written by Devin with a little bit of review from me. Happy to address any feedback and get this over the finish line.
