Enum Durability 

pub enum Durability {
    Sync,
    Async,
    Exit,
}

Checkpoint durability mode

Determines how checkpoint writes are synchronized to storage backends. Higher durability guarantees come at the cost of increased latency.

Variants

Sync

Synchronous checkpoint writes (default)

Each checkpoint is fully written to storage before the next superstep begins. Provides the strongest durability guarantee.

Async

Asynchronous checkpoint writes

Checkpoint writes are submitted to storage but execution continues without waiting for confirmation. Durability depends on the storage backend’s write-behind behavior.

Exit

No checkpoint persistence

Checkpoints are not persisted to external storage. Used for ephemeral or development runs where durability is not required.

Trait Implementations

impl Clone for Durability

fn clone(&self) -> Durability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Durability

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

Formats the value using the given formatter.

impl Default for Durability

fn default() -> Durability

Returns the “default value” for a type.

impl PartialEq for Durability

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