Enum When 

pub enum When {
    PerPc(PerPolicy),
    PerTarget(PerPolicy),
    Cron(String),
}

#418 Phase 1 — the single “when does this fire” axis.

Replaces the old cron + mode + cooldown trio whose interactions were implicit (cron doubled as both a real time-of-day trigger and a reconcile poll period; contradictory combinations silently no-opped). Two shapes:

• reconcile (per_pc / per_target) — desired-state: “each pc (or one delegate) should have run this within every”. The poll period is system-generated (POLL_CRON, every minute) and no longer the operator’s concern.
• escape hatch (cron) — verbatim 6-field cron, fires at the whole target on every tick with no dedup (the old every_tick). Temporary: exists only to keep time-of-day schedules (morning-greeting) alive until the Phase 2 calendar form (at / days / tz) lands. New reconcile work must NOT use it.

Variants

PerPc(PerPolicy)

Fire at each targeted pc: once (kitting — succeed once, skip forever, forever catching brand-new / re-imaged pcs) or { every: <humantime> } (patrol — re-arm per pc after the interval).

PerTarget(PerPolicy)

Fire until any one pc of the target succeeds, then skip the whole target (once) or re-arm after every. Needs fleet-wide completion data, so it is backend-only — runs_on: agent + per_target is rejected by Schedule::validate.

Cron(String)

Escape hatch: verbatim 6-field cron expression (sec min hour day month day-of-week), validated with the same parser tokio-cron-scheduler uses. Every tick fires the whole target — no dedup, no cooldown.

Trait Implementations

impl Clone for When

fn clone(&self) -> When

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for When

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for When

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for When

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Operator-facing one-liner (per_pc once / per_pc every 6h / cron: 0 0 9 * * mon-fri) for log lines, audit payloads and the API’s ScheduleSummary.

impl Eq for When

impl JsonSchema for When

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for When

fn eq(&self, other: &When) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for When

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
