Struct Backend 

pub struct Backend(/* private fields */);

A process-local proof that Catalejo’s linked fault routines are published.

NOTE(invariant): raw is returned only by the C singleton after it has created and published the default slab for process_id. A protected operation compares process_id with the calling process before relying on the singleton, so an inherited handle cannot prove recovery after fork.

Implementations

impl Backend

pub unsafe fn initialize(device: BorrowedFd<'_>) -> Result<Self>

Initialize or reuse the process backend through a Mirilla descriptor.

Safety

device must be a descriptor created by Mirilla.

Errors

This returns creation, mapping, loading, publication, or stale-rebuild failures.

pub fn retrieve() -> Result<Self>

Retrieve the backend initialized for the calling pid.

Errors

This returns not-found before initialization and stale in a fork child.

pub fn validate(&self) -> Result<()>

Verify that this backend was published for the calling process.

Errors

This returns stale when the handle was inherited across fork.
