Enum CheckpointGranularity 

#[non_exhaustive]
pub enum CheckpointGranularity {
    Off,
    PerNode,
}

How often the compiled graph writes a checkpoint when a Checkpointer is attached.

PerNode (the default) writes after every successful node completion — durable enough that a crash mid-graph loses at most one node’s work. Off skips checkpointer writes entirely; the graph still runs end-to-end but cannot resume after a crash.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Off

Skip checkpointer writes. Useful for ephemeral graphs or when the checkpointer is attached purely to satisfy a downstream API contract.

PerNode

Write a checkpoint after each node completes successfully. This is the default and matches the F8 mitigation.

Trait Implementations

impl Clone for CheckpointGranularity

fn clone(&self) -> CheckpointGranularity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckpointGranularity

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

Formats the value using the given formatter.

impl Default for CheckpointGranularity

fn default() -> CheckpointGranularity

Returns the “default value” for a type.

impl Hash for CheckpointGranularity

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CheckpointGranularity

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