Enum GuardPolicy 

pub enum GuardPolicy {
    BestEffort,
    Require,
    Disable,
}

Requested guard-band behavior around an endpoint’s own active view mapping.

Guard bands are inaccessible address ranges installed immediately before and after each endpoint’s own active view mapping when a committed batch maps its views. They contain in-process linear overruns past a view. They do not constrain the peer’s own address space, and they do not constrain aliases created by a hostile holder of delegated native capability.

The creating endpoint honors the policy requested for the region. The receiving endpoint always applies best-effort installation, because the wire manifest does not carry the policy.

Variants

BestEffort

Install guard bands where reliable placement is available and report the outcome honestly instead of failing.

Require

Fail batch preparation or commit on the creating endpoint unless its own view mappings receive guard bands.

Disable

Do not request guard bands on the creating endpoint.
