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.
• 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

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

use zerocopy_derive::*;

// The only valid value of this type are the bytes `0xC0C0`.
#[derive(TryFromBytes, KnownLayout, Immutable)]
#[repr(u16)]
pub enum C0C0 {
    _XC0C0 = 0xC0C0,
}

#[derive(FromBytes, KnownLayout, Immutable, SplitAt)]
#[repr(C, align(4))]
pub struct Packet<Magic> {
    magic_number: Magic,
    milk: u8,
    mug_size: u8,
    temperature: [u8; 5],
    marshmallows: [[u8; 3]],
}

/// A packet begining with the magic number `0xC0C0`.
pub type CocoPacket = Packet<C0C0>;

/// A packet beginning with any two initialized bytes.
pub type LocoPacket = Packet<[u8; 2]>;

Annotation

• Atlas domain: Rust Kernel Layer / Rust API Membrane.
• 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.
