Enum WrapperSubject 

pub enum WrapperSubject<'a> {
    Op(&'a ParsedOp),
    Phase(&'a WorkloadPhase),
}

SRD-82/92 — the execution unit a wrapper’s trigger inspects, generalising the registry across levels. An op wrapper reads the Op variant; a phase wrapper the Phase variant (scenario/session variants join when those levels wire up). Op-level wrappers guard with Self::op; the resolver only offers a wrapper subjects of the level it declares (applies_at), so a well-formed wrapper never sees a foreign subject — the guard is a belt-and-braces None return.

Variants

Op(&'a ParsedOp)

Phase(&'a WorkloadPhase)

Implementations

impl<'a> WrapperSubject<'a>

pub fn level(&self) -> WrapperLevel

The execution level of this subject; pairs with WrapperRegistration::applies_at.

pub fn op(&self) -> Option<&'a ParsedOp>

The op template, if this is an op subject (op-wrapper triggers guard on it).

pub fn phase(&self) -> Option<&'a WorkloadPhase>

The phase, if this is a phase subject (phase-wrapper triggers guard on it).

pub fn has_owned_field(&self, field: &str) -> bool

Uniform “is this wrapper-owned field present?” — the canonical field names mapped to each unit’s actual storage. Op fields are spread across params/condition/delay/rate; phase fields are typed slots. Used by the parse-time misplaced-field guard.

Trait Implementations

impl<'a> Clone for WrapperSubject<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
