Enum TriggerPolicy 

pub enum TriggerPolicy {
    EveryNode,
    BarrierOnly,
    Manual,
    OnMutation,
}

Checkpoint 触发策略 — 决定何时保存。

Variants

EveryNode

每次节点执行后保存（默认，与 v0.4 CheckpointPolicy::EveryNode 一致）

BarrierOnly

仅在 Barrier 决策后保存

Manual

手动控制 — 调用方显式触发

OnMutation

有新 Mutation 时才保存（无 Mutation 的节点跳过）

Trait Implementations

impl Clone for TriggerPolicy

fn clone(&self) -> TriggerPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TriggerPolicy

impl Debug for TriggerPolicy

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

Formats the value using the given formatter.

impl Default for TriggerPolicy

fn default() -> TriggerPolicy

Returns the “default value” for a type.

impl Eq for TriggerPolicy

impl From<CheckpointPolicy> for TriggerPolicy

fn from(policy: CheckpointPolicy) -> Self

Converts to this type from the input type.

impl PartialEq for TriggerPolicy

fn eq(&self, other: &TriggerPolicy) -> 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.
