Enum ExecutionMode 

pub enum ExecutionMode {
    Replaying,
    Executing,
}

Signal whether the replay engine is replaying from history or executing new operations.

During replay, durable operations return cached results from the history log without re-executing. Once the cursor advances past all history entries, the mode transitions to Executing and new operations run and checkpoint their results.

The history data and cursor position are owned by the replay engine (replay.rs), not by this enum.

Examples

use durable_lambda_core::types::ExecutionMode;

let mode = ExecutionMode::Replaying;
assert_eq!(mode, ExecutionMode::Replaying);

let mode = ExecutionMode::Executing;
assert_eq!(mode, ExecutionMode::Executing);

Variants

Replaying

The engine is replaying operations from cached history.

Executing

The engine is executing new operations and checkpointing results.

Trait Implementations

impl Clone for ExecutionMode

fn clone(&self) -> ExecutionMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExecutionMode

fn deserialize<__D>( __deserializer: __D, ) -> Result<ExecutionMode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ExecutionMode

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
