Trait NativePhysicalExitCompletion 

pub unsafe trait NativePhysicalExitCompletion {
    // Required methods
    fn retained_pidfd(&self) -> BorrowedFd<'_>;
    fn process_id(&self) -> i32;
    fn birth_identity(&self) -> u64;
}

Actual physical exit-watch completion carried by a private affine backend receipt, not a caller’s assertion that an exit happened.

Safety

Implement only on a private type constructed after the real watched birth’s PhysicalExitWatch drain completed, its one physical report was delivered, and all watch failures were excluded. Retain that same pidfs pidfd and IDs. Numerical PID equality, child wait alone, source EOF, or a bool cannot create this receipt. The host implementation additionally checks the actual fd below.

Required Methods

fn retained_pidfd(&self) -> BorrowedFd<'_>

The same retained watched pidfd, owned by this affine receipt.

fn process_id(&self) -> i32

Actual deterministic/physical root PID of the single-thread domain.

fn birth_identity(&self) -> u64

Independently retained pidfs inode of that watched birth.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
