Why This File Exists

Rust-side wrappers and abstractions around kernel C APIs, ownership contracts, allocation, synchronization, and module integration.

• Rust-side wrappers and abstractions around kernel C APIs, ownership contracts, allocation, synchronization, and module integration.
• Touches user memory; correctness depends on fault-safe copying and privilege boundary handling.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• function Ok

Annotated Snippet

fn drop(&mut self) {
        // SAFETY: By the type invariants, we have ownership of the page and can free it.
        unsafe { bindings::__free_pages(self.page.as_ptr(), 0) };
    }
}

Annotation

• Detected declarations: `function Ok`.
• Atlas domain: Rust Kernel Layer / Rust API Membrane.
• Implementation status: source implementation candidate.
• This snippet crosses the user/kernel memory boundary; validate fault handling and access checks before translating the pattern.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
