  • Add share_access into FileCreateArgs struct.
  • Managing share_access is now manual and is false to all read, write, delete by default
  • Make ShareAccessFlags into public api

I had a real technical problem, where I needed to manage share access to files. And from the code of your repo I don't see how I can do it. So I added it for my own usage, but I hope that even if this pr will not get to main, you'll eventually add managing share access in your next commits

Summary by CodeRabbit

  • New Features
    • Added support for configuring share access flags when creating files, directories, and other resources.
    • Exposed share access settings through the public SMB interface.
    • Resource creation now consistently honors the specified share access configuration.

Review Change Stack

Walkthrough

ShareAccessFlags is explicitly re-exported at the crate root. FileCreateArgs now carries share access settings, and resource and tree creation paths pass empty flags into SMB create requests.

Changes

Share access propagation

Layer / File(s) Summary
Share access contract
crates/smb/src/lib.rs, crates/smb/src/resource.rs
The crate root explicitly re-exports ShareAccessFlags. FileCreateArgs stores the field and initializes it to empty flags in its constructors.
Share access request wiring
crates/smb/src/resource.rs, crates/smb/src/tree.rs
Resource::create forwards create_args.share_access. File and directory creation wrappers initialize the field with empty flags.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 79fd1

This change adds caller-controlled share access but also makes existing file-creation helpers deny concurrent read, write, delete, and rename opens by default, which can disrupt applications that rely on shared access. Adding a required public field may also break downstream consumers at compile time, so the PR needs explicit compatibility or migration handling before merge.

Poem

A rabbit checks the flags with care

Empty shares now travel there
Through file and directory doors
The request carries what it stores
Hop, hop—the crate exports more

Document the expanded FileCreateArgs contract.

FileCreateArgs has no structure or field documentation, and Tree::create does not describe share_access. Add the purpose, an MS-SMB2 index-format specification reference, and concise documentation for the critical fields. Describe the sharing behavior without listing constants or reserved fields.

As per coding guidelines, structure documentation must include a brief purpose, an MS-SMB2 index-format specification reference, and critical field documentation.

Avoid an unversioned breaking change to FileCreateArgs.

FileCreateArgs is public and re-exported by smb. Adding required share_access makes existing downstream struct literals fail to compile. If this release is not intentionally breaking, preserve struct-literal compatibility. Otherwise, document the migration and publish with a version that signals the breaking change instead of 0.11.2.

@Runeville I support this comment, despite a minor AI hate I got these days. It'll have to wait for #172 to get merged, and I'll consider fixing the interface of this structure anyway.
