Enum SopAdmissionPolicy 

pub enum SopAdmissionPolicy {
    Parallel,
    Hold,
    Coalesce,
    Drop,
}

How concurrent triggers are handled when a SOP’s execution slots are full. A run parked at a HITL approval releases its slot (A1), so this governs the remaining case: too many runs actively executing at once. No variant ever silently drops a trigger except Drop, which is explicit opt-in.

Variants

Parallel

Admit up to max_concurrent concurrent runs; a trigger that cannot admit now is DEFERRED (surfaced for backpressure/redelivery), never silently dropped. Best fit for independent work like PR-request approvals.

Hold

Serialize: admit only when no run of this SOP is active or parked; other triggers are deferred. For pipelines whose pre-approval steps must not overlap.

Coalesce

Collapse concurrent triggers: when a run is already in flight for this SOP a new trigger is coalesced (dropped as redundant - the in-flight run already covers the latest state). For “only current state matters” SOPs.

Drop

Legacy fire-and-forget: a trigger that cannot admit now is dropped. Explicit opt-in only; never the default.

Trait Implementations

impl Clone for SopAdmissionPolicy

fn clone(&self) -> SopAdmissionPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SopAdmissionPolicy

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

Formats the value using the given formatter.

impl Default for SopAdmissionPolicy

fn default() -> SopAdmissionPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SopAdmissionPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SopAdmissionPolicy

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

Formats the value using the given formatter.

impl JsonSchema for SopAdmissionPolicy

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 SopAdmissionPolicy

fn eq(&self, other: &SopAdmissionPolicy) -> 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 SopAdmissionPolicy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
