source implementation candidate

Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• 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

• struct Buf

Annotated Snippet

struct Buf {
    data1: u64,
    data2: String,
    data3: u64,
}

#[no_mangle]
pub extern "C" fn test_rs(count: u32) {
    let mut b = Buf {
        data1: 0,
        data2: String::from("data"),
        data3: 0,
    };

    for _ in 1..count {
        b.data1 += 1;
        if b.data1 == 123 {
            b.data1 += 1;
        }

        b.data3 += b.data1;
    }
}

Annotation

• Detected declarations: `struct Buf`.
• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: source implementation candidate.

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.
