Enum Mode 

pub enum Mode {
    Persistent,
    Ephemeral,
}

DBSP circuit execution mode.

Variants

Persistent

Operators in the circuit have persistent id’s.

In this mode, operators are assigned persistent id’s by the compiler. These id’s are preserved across circuit restarts for parts of the circuit that remain unmodified. This allows the circuit to partially or completely restore its state from a checkpoint.

In persistent mode, the circuit may fail to start if not all operators are assigned persistent id’s.

Ephemeral

Circuit operators are assigned ephemeral id’s.

In this mode, operators are not assigned persistent id’s. The circuit can only restore its state from a checkpoint if the entire circuit is unmodified.

Trait Implementations

impl Clone for Mode

fn clone(&self) -> Mode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mode

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

Formats the value using the given formatter.

impl Default for Mode

fn default() -> Mode

Returns the “default value” for a type.

impl PartialEq for Mode

fn eq(&self, other: &Mode) -> 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 Eq for Mode
